The ADF4002 frequency synthesizer is used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It consists of a low-noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider and programmable N divider. The 14-bit reference counter (R counter), allows selectable REFIN frequencies at the PFD input.A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). In addition, by programming R and N to 1, the device can be used as a standalone PFD and charge pump.The ADF4002-EP supports defense and aerospace applications (AQEC standard).

The AD8290 contains both an adjustable current source to drive a sensor and a difference amplifier to amplify the signal voltage. The amplifier is set for a fixed gain of 50. The AD8290 is an excellent solution for both the drive and the sensing aspects required for pressure, temperature, and strain gage bridges.In addition, because the AD8290 operates with low power, works with a range of low supply voltages, and is available in a low profile package, it is suitable for drive/sense circuits in portable electronics as well. The AD8290 is available in a lead free 3.0 mm × 3.0 mm × 0.55 mm package and is operational over the industrial temperature range of −40°C to +85°C.Applications Bridge and sensor drives Portable electronics

The ADV7390?/?ADV7391?/?ADV7392?/ ADV7393?are a family of high speed, digital-to-analog video encoders on single monolithic chips. Three 2.7 V/3.3 V, 10-bit video DACs (a single DAC for the WLCSP package) provide support for composite (CVBS), S-Video (Y-C), or component (YPrPb/RGB) analog outputs in either standard definition (SD) or high definition (HD) video formats. The single DAC WLCSP package supports CVBS (NTSC and PAL) output only in SD resolution (see Table 2).Optimized for low power operation, occupying a minimal footprint, and requiring few external components, these encoders are ideally suited to portable and power-sensitive applications requiring TV-out functionality. Cable detection and DAC auto power-down features ensure that power consumption is kept to a minimum.The ADV7390 / ADV7391 have an 8-bit video input port that supports SD video formats over an SDR interface and HD video formats over a DDR interface. The ADV7392 / ADV7393 have a 16-bit video input port that can be configured in a variety of ways. SD RGB input is supported.All members of the family support embedded EAV/SAV timing codes, external video synchronization signals, and the I2C? and communication protocol. Table 1 and Table 2 list the video standards directly supported by the ADV7390/ADV7391/ ADV7392/ADV7393 family.APPLICATIONS Mobile handsets Digital still cameras Portable media and DVD players Portable game consoles Digital camcorders Set-top box (STB) Automotive infotainment (ADV7392 and ADV7393 only)

The AD7705 / AD7706?are complete analog front ends for low frequency measurement applications. These 2-/3-channel devices can accept low level input signals directly from a transducer and produce serial digital output. The devices employ a ?-? conversion technique to realize up to 16 bits of no missing codes performance. The selected input signal is applied to a proprietary, programmable-gain front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. The first notch of this digital filter can be programmed via an on-chip control register, allowing adjustment of the filter cutoff and output update rate. The AD7705 / AD7706 devices operate from a single 2.7 V to 3.3 V or 4.75 V to 5.25 V supply. The AD7705 features two fully differential analog input channels; the AD7706 features three pseudo differential input channels. Both devices feature a differential reference input. Input signal ranges of 0 mV to 20 mV through 0 V to 2.5 V can be incorporated on both devices when operating with a VDD of 5 V and a reference of 2.5 V. They can also handle bipolar input signal ranges of ?20 mV through ?2.5 V, which are referenced to the AIN(?) inputs on the AD7705 and to the COMMON input on the AD7706.The AD7705 / AD7706 devices, with a 3 V supply and a 1.225 V reference, can handle unipolar input signal ranges of 0 mV to 10 mV through 0 V to 1.225 V. The devices can accept bipolar input ranges of ?10 mV through ?1.225 V. Therefore, the AD7705 / AD7706 devices perform all signal conditioning and conversion for a 2-channel or 3-channel system. The AD7705 / AD7706 are ideal for use in smart, microcontroller, or DSP-based systems. The devices feature a serial interface that can be configured for 3-wire operation. Gain settings, signal polarity, and update rate selection can be configured in software using the input serial port. The parts contains self-calibration and system calibration options to eliminate gain and offset errors on the part itself or in the system. CMOS construction ensures very low power dissipation, and the power-down mode reduces the standby power consumption to 20 ?W typ. These parts are available in a 16-lead, wide body (0.3 inch), plastic dual in-line package (DIP); a 16-lead, wide body (0.3 inch), standard small outline (SOIC) package; and a low profile, 16-lead, thin shrink small outline package (TSSOP).

The ADuM3400/ADuM3401/ADuM3402 are 4-channel digitalisolators based on the Analog Devices, Inc., iCoupler® technology.Combining high speed CMOS and monolithic air coretransformer technology, these isolation components provideoutstanding performance characteristics superior to alternativessuch as optocoupler devices.iCoupler devices remove the design difficulties commonlyassociated with optocouplers. Typical optocoupler concernsregarding uncertain current transfer ratios, nonlinear transferfunctions, and temperature and lifetime effects are eliminatedwith the simple iCoupler digital interfaces and stable performancecharacteristics. The need for external drivers and other discretecomponents is eliminated with these iCoupler products. Furthermore,iCoupler devices consume one-tenth to one-sixth thepower of optocouplers at comparable signal data rates.The isolators provide four independent isolation channels in avariety of channel configurations and data rates (see theOrdering Guide). All models operate with the supply voltage oneither side ranging from 2.7 V to 5.5 V, providing compatibilitywith lower voltage systems as well as enabling a voltagetranslation functionality across the isolation barrier. Theisolators have a patented refresh feature that ensures dc correctnessin the absence of input logic transitions and during powerup/power-downconditions.In comparison to the ADuM1400/ADuM1401/ADuM1402isolators, the ADuM3400/ADuM3401/ADuM3402 isolatorscontain various circuit and layout changes to provide increasedcapability relative to system-level IEC 61000-4-x testing (ESD/burst/surge). The precise capability in these tests for either set ofisolators is strongly determined by the design and layout of theuser’s board or module.

The AD8221 is a gain programmable, high performance instrumentation amplifier that delivers the industry’s highest CMRR over frequency in its class. The CMRR of instrumentation amplifiers on the market today falls off at 200 Hz. In contrast, the AD8221 maintains a minimum CMRR of 80 dB to 10 kHz for all grades at G = 1. High CMRR over frequency allows the AD8221 to reject wideband interference and line harmonics, greatly simplifying filter requirements. Possible applications include precision data acquisition, biomedical analysis, and aerospace instrumentation. Low voltage offset, low offset drift, low gain drift, high gain accuracy, and high CMRR make this part an excellent choice in applications that demand the best dc performance possible, such as bridge signal conditioning. Programmable gain affords the user design flexibility. A single resistor sets the gain from 1 to 1000. The AD8221 operates on both single and dual supplies and is well suited for applications where ±10 V input voltages are encountered. The AD8221 is available in a low cost 8-lead SOIC and 8-lead MSOP, both of which offer the industry’s best performance. The MSOP requires half the board space of the SOIC, making it ideal for multichannel or space-constrained applications. Performance is specified over the entire industrial temperature range of −40°C to +85°C for all grades. Furthermore, the AD8221 is operational from −40°C to +125°C*.
