The AD724 is a low cost RGB to NTSC/PAL Encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined to provide composite video output. All three outputs can simultaneously drive 75 (ohm), reverse-terminated cables. All logical inputs are CMOS compatible. The chip operates from a single +5 V supply. No external delay lines or filters are required. The AD724 may be powered down when not in use.The AD724 accepts either FSC or 4FSC clock. When a clock is not available, a low cost parallel-resonant crystal (3.58 MHz (NTSC) or 4.43 MHz (PAL)) and the AD724?s on-chip oscilla-tor generate the necessary subcarrier clock. The AD724 also accepts the subcarrier clock from an external video source.The interface to graphics controllers is simple: an on-chip logic ?XNOR? accepts the available vertical (VSYNC) and horizontal sync (HSYNC) signals and creates the composite sync (CSYNC) signal on-chip. If available, the AD724 will also accept a standard CSYNC signal by connecting VSYNC to +5 V and applying CSYNC to the HSYNC pin. The AD724 contains decoding logic to identify valid horizontal sync pulses for correct burst insertion.Delays in the U and V chroma filters are matched by an on-chip sampled-data delay line in the Y signal path. To prevent aliasing, a prefilter at 5 MHz is included ahead of the delay line and a post-filter at 5 MHz is added after the delay line to suppress harmonics in the output. These low-pass filters are optimized for minimum pulse overshoot. The overall luma delay, relative to chroma, has been designed to be time aligned for direct input to a television?s baseband. The AD724 comes in a space-saving SOIC and is specified for the 0?C to +70?C commercial temperature range.An evaluation board is available for this product and may be ordered using the following product number: AD724-EB.

The AD8013 is a low power, single supply, triple video amplifier. Each of the three amplifiers has 30 mA of output current, and is optimized for driving one back terminated video load (150 ?) each. Each amplifier is a current feedback amp-lifier and features gain flatness of 0.1 dB to 60 MHz while offering differential gain and phase error of 0.02% and 0.06? This makes the AD8013 ideal for broadcast and professional video electronics.The AD8013 offers low power of 4 mA per amplifier max and runs on a single +5 V to +13 V power supply. The outputs of each amplifier swing to within one volt of either supply rail to easily accommodate video signals. The AD8013 is unique among current feedback op amps by virtue of its large capacitive load drive. Each op amp is capable of driving large capacitive loads while still achieving rapid settling time. For instance it can settle in 18 ns driving a resistive load, and achieves 40 ns (0.1%) settling while driving 200 pF.The outstanding bandwidth of 150 MHz along with 1000 V/?s of slew rate make the AD8013 useful in many general purpose high speed applications where a single +5 V or dual power supplies up to ?6.5 V are required. Furthermore the AD8013's high speed disable function can be used to power down the amplifier or to put the output in a high impedance state. This can then be used in video multiplexing applications. The AD8013 is available in the industrial temperature range of -40?C to +85?C.

The AD8074 /AD8075 are high-speed triple video buffers with a G = +1 and +2 respectively. They operate on ?5V and have a -3dB full signal bandwidth in excess of 500MHz, along with slew rates in excess of 1350V/?s. With better than -80dB of all hostile crosstalk and 90dB isolation, they are useful in many high-speed applications. The differential gain and differential phase error are 0.01% and 0.01?. Gain Flatness of 0.1dB up to 70MHz make the AD8074/75 ideal for RGB buffering or driving. They consume less than 30mA on a ?5V supply voltage.Both devices offer a high-speed disable feature that allows the outputs to be put into a high impedance state. This allows the building of larger input arrays while minimizing 'OFF' channel output loading. The AD8074/75 are offered in a 16 lead TSSOP package.

The AD8113 is a fully buffered crosspoint switch matrix that operates on ?12V for Audio applications and ?5V for Video applications. It offers a -3dB signal bandwidth greater than 60MHz and channel switch times of less than 60ns with 0.1% settling for use in both analog and digital audio. The AD8113 operated at 20kHz has crosstalk performance of -83dB and isolation of 90dB. In addition, ground/power pins surround all inputs and outputs to provide extra shielding for operation in the most demanding audio routing applications. The differential gain and differential phase of better than 0.1% and 0.1?, respectively, along with 0.1dB flatness out to 10MHz make the AD8113 suitable for many video applications.The AD8113 includes 16 independent output buffers that can be placed into a disabled state for paralleling crosspoint outputs so that off channel loading is minimized. The AD8113 has a gain of +2. It operates on voltage supplies of ?5V or ?12V while consuming only 34mA or 31mA of current, respectively.The channel switching is performed via a serial digital control (which can accommodate daisy-chaining of several devices) or via a parallel control, allowing updating of an individual output without reprogramming the entire array.The AD8113 is packaged in a 100-lead LQFP and is available over the commercial temperature range of 0?C to 70?C.

The AD8129/AD8130 are designed as receivers for the transmission of high speed signals over twisted-pair cables to work with the AD8131 or AD8132 drivers. Either can be used for analog or digital video signals and for high speed data transmission. The AD8129/AD8130 are differential-to-single-ended amplifiers with extremely high CMRR at high frequency. Therefore, they canalso be effectively used as high speed instrumentation amps or for converting differential signals to single-ended signals.The AD8129 is a low noise, high gain (10 or greater) version intended for applications over very long cables, where signal attenuation is significant. The AD8130 is stable at a gain of 1 and can be used for applications where lower gains are required. Both have user-adjustable gain to help compensate for losses in the transmission line. The gain is set by the ratio of two resistor values. The AD8129/AD8130 have very high input impedance on both inputs, regardless of the gain setting. The AD8129/AD8130 have excellent common-mode rejection (70 dB @ 10 MHz), allowing the use of low cost, unshielded twisted-pair cables without fear of corruption by external noise sources or crosstalk. The AD8129/AD8130 have a wide power supply range from single +5 V to ?12 V, allowing wide common-mode and differential-mode voltage ranges while maintaining signal integrity. The wide common-mode voltage range enables the driver-receiver pair to operate without isolation transformers in many systems where the ground potential difference between drive and receive locations is many volts. The AD8129/AD8130 have considerable cost and performance improvements over op amps and other multiamplifier receiving solutions.

The AD8158 has low latency and very low lane-to-lane skew.The main application of the AD8158 is to support redundancy on both the backplane and the line interface sides of a serial link. The demultiplexing path implements unicast and bicast capability, allowing the part to support either 1 + 1 or 1:1 redundancy.The AD8158 is also suited for testing high speed serial links because of its ability to duplicate incoming data. In a port-monitoring application, the AD8158 can maintain link-connectivity with a pass-through connection from Port C to Port A while sending a duplicate copy of the data to test equipment on Port B.The rich feature set of the AD8158 can be controlled either through external toggle pins or by setting on-chip control registers through the I2C interface.APPLICATIONS Low cost redundancy switch SONET OC48/SDH16 and lower data rates XAUI/GbE/FC/Infiniband over backplane OIF CEI 6.25 Gbps over backplane Serial data-level shift 4-/8-/12-lane equalizers or redrivers

The AD823A is a dual precision, 17 MHz, JFET input op amp manufactured in the extra fast complementary bipolar (XFCB) process. The AD823A can operate from a single supply of 3 V to 36 V or from dual supplies of ?1.5 V to ?18 V. It has true single-supply capability with an input voltage range extending below ground in single-supply mode. Output voltage swing extends to within 20 mV of each rail for IOUT ? 100 ?A, providing outstanding output dynamic range. It also has a linear output current of 40 mA, 0.5 V from the supply rails.An offset voltage of 700 ?V maximum, an offset voltage drift of 1 ?V/?C, and typical input bias currents of 0.3 pA provide dc precision with source impedances up to 1 G?. The AD823A provides 17 MHz, ?3 dB bandwidth, and a 30 V/?s slew rate with a low supply current of only 2.6 mA per amplifier. It also provides low input voltage noise of 14 nV/?Hz and ?108 dB SFDR at 20 kHz. The AD823A has low input capacitances (0.6 pF differential and 1.3 pF common mode) and drives more than 500 pF of direct capacitive load as a follower. This lets the amplifier handle a wide range of load conditions.This combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile amplifier for applications such as ADC drivers, high speed active filters, and other low voltage, high dynamic range systems.The AD823A is available over the industrial temperature range of ?40?C to +85?C and is offered in an 8-lead SOIC package and an 8-lead MSOP package.APPLICATIONS Battery-powered precision instrumentation Photodiode preamps Active filters 12-bit to 16-bit data acquisition systems Medical instrumentation

The AD8244 is a precision, low power, FET input, quad unity-gain buffer that is designed to isolate very large source impedances from the rest of the signal chain. The 2 pA maximum bias current, near zero current noise, and 10 T? input impedance introduce almost no error, even with source impedance well into the megaohms.Many traditional operational amplifier pinouts have a supply pin that is next to the noninverting input. A guard trace must be routed between these pins to avoid leakage currents much larger than the bias current of a FET input op amp. Guard traces can be routed between pins for large packages, such as DIP or even SOIC; however, the board area consumed by these packages is prohibitive for many modern applications. The AD8244 solves this problem with a unique pinout that physically separates the high impedance inputs from the low impedance supplies and outputs of the other buffers. This configuration simplifies guarding while reducing board space, allowing high performance and high density in the same design.The AD8244 design is focused on solving problems specific to buffers. This includes close channel-to-channel matching which allows channels of the AD8244 to be used in differential signal chains with minimal error. With its low voltage noise, wide supply range, and high precision, the AD8244 is also flexible enough to provide high performance anywhere a unity-gain buffer is needed, even with low source resistance.The AD8244 is specified over the industrial temperature range of ?40?C to +85?C. It is available in a 10-lead MSOP package.APPLICATIONSBiopotential electrodesMedical instrumentationHigh impedance sensor conditioningFiltersPhotodiode amplifiers

It has high bandwidth of 10 MHz, low THD of ?110 dB, and fast settling time of 785 ns (maximum) to 0.001%. Offset drift and gain drift are guaranteed to 1.8 ?V/?C and 10 ppm/?C, respectively, for G = 8. In addition to its wide input common voltage range, it boasts a high common-mode rejection of 80 dB at G = 1 from dc to 50 kHz. The combination of precision dc performance coupled with high speed capabilities makes the AD8251 an excellent candidate for data acquisition. Furthermore, this monolithic solution simplifies design and manufacturing and boosts performance of instrumentation by maintaining a tight match of internal resistors and amplifiers. The AD8251 user interface consists of a parallel port that allows users to set the gain in one of two different ways (see Figure 1 in data sheet for the functional block diagram). A 2-bit word sent via a bus can be latched using the WR input. An alternative is to use transparent gain mode where the state of logic levels at the gain port determines the gain. The AD8251 is available in a 10-lead MSOP package and is specified over the ?40?C to +85?C temperature range, making it an excellent solution for applications where size and packing density are important considerations.
