The AD7896 is a fast, 12-bit ADC that operates from a single 2.7 V to 5.5 V supply and is housed in small 8-lead PDIP and 8-lead SOIC packages. The part contains an 8 µs successive approximation ADC, an on-chip track-and-hold amplifier, an on-chip clock, and a high speed serial interface.Output data from the AD7896 is provided via a high speed, serial interface port. This 2-wire serial interface has a serial clock input and a serial data output with the external serial clock accessing the serial data from the part.In addition to the traditional dc accuracy specifications, such as linearity, full-scale, and offset errors, the AD7896 is also specified for dynamic performance parameters, including harmonic distortion and signal-to-noise ratio.The part accepts an analog input range of 0 V to VDD and operates from a single 2.7 V to 5.5 V supply, consuming only 9 mW typical. The VDD input is also used as the reference for the part so that no external reference is required.The AD7896 features a high sampling rate mode and, for low power applications, a proprietary automatic power down mode where the part automatically goes into power down once con-version is complete and 'wakes up' before the next conversion cycle.The part is available in a small, 8-lead, 0.3'' wide, plastic or hermetic dual-in-line package (PDIP) and in an 8-lead, small outline IC (SOIC).PRODUCT HIGHLIGHTS Complete, 12-bit ADC in an 8-Lead Package. The AD7896 contains an 8 µs ADC, a track-and-hold amplifier, control logic, and a high speed serial interface, all in an 8-lead PDIP. The VDD input is used as the reference for the part, so no external reference is needed. This offers considerable space saving over alternative solutions. Low Power, Single-Supply Operation. The AD7896 operates from a single 2.7 V to 5.5 V supply and consumes only 9 mW typical. The automatic powerdown mode, where the part goes into power down once conversion is complete and “wakes up” before the next conversion cycle, makes the AD7896 ideal for battery-powered or portable applications. High Speed Serial Interface. The part provides high speed serial data and serial clock lines allowing for an easy, 2-wire serial interface arrangement.

The AD7904 / AD7914 / AD7924 are, respectively, 8-bit, 10-bit, and 12-bit, high speed, low power, 4-channel successive approximation ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 8 MHz.The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the device to easily inter-face with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and conversion is also initiated at this point. There are no pipeline delays associated with the part.The AD7904 / AD7914 / AD7924 use advanced design techniques to achieve very low power dissipation at maximum throughput rates. At maximum throughput rates, the AD7904 / AD7914 / AD7924 consume 2 mA maximum with 3 V supplies; with 5 V supplies, the current consumption is 2.7 mA maximum.Through the configuration of the control register, the analog input range for the part can be selected as 0 V to REFIN or 0 V to 2 × REFIN, with either straight binary or twos complement output coding. The AD7904 / AD7914 / AD7924 each feature four single-ended analog inputs with a channel sequencer to allow a pre-programmed selection of channels to be converted sequentially.The conversion time for the AD7904 / AD7914 / AD7924 is determined by the SCLK frequency, which is also used as the master clock to control the conversion.PRODUCT HIGHLIGHTS High Throughput with Low Power Consumption. The AD7904/AD7914/AD7924 offer throughput rates up to 1 MSPS. Four Single-Ended Inputs with Channel Sequencer. A consecutive sequence of channels can be selected, through which the ADC will cycle and convert on. Single-Supply Operation with VDRIVE Function. The AD7904/AD7914/AD7924 operate from a single 2.7 V to 5.25 V supply. The VDRIVE function allows the serial interface to connect directly to 3 V or 5 V processor systems, independent of VDD. Flexible Power/Serial Clock Speed Management. The conversion rate is determined by the serial clock, allowing the conversion time to be reduced by increasing the serial clock speed. The parts also feature two shutdown modes to maximize power efficiency at lower throughput rates. Current consumption is 0.5 µA maximum when in full shutdown. No Pipeline Delay. The parts feature a standard successive approximation ADC with accurate control of the sampling instant via the CS input and once-off conversion control.

The AD797 is a very low noise, low distortion operational amplifier ideal for use as a preamplifier. The low noise of 0.9 nV√Hz and low total harmonic distortion of -120 dB at audio bandwidths give the AD797 the wide dynamic range necessary for preamps in microphones and mixing consoles.Furthermore, the AD797's excellent slew rate of 20 V/µs and 110 MHz gain bandwidth make it highly suitable for low frequency ultrasound applications.The AD797 is also useful in IR and Sonar Imaging applications where the widest dynamic range is necessary. The low distortion and 16-bit settling time of the AD797 make it ideal for buffering the inputs to Sigma Delta ADCs or the outputs of high resolution DACs especially when they are used in critical applications such as seismic detection and spectrum analyzers. Key features such as a 50 mA output current drive and the specified power supply voltage range of ±5 to ±15 volts make the AD797 an excellent general purpose amplifier.APPLICATIONS Professional audio preamplifiers IR, CCD, and sonar imaging systems Spectrum analyzers Ultrasound preamplifiers Seismic detectors Σ-Δ ADC/DAC buffers

The I2C interface on the AD7994-0 supports Standard and Fast I2C Interface Modes. The I2C interface on the AD7994-1 supports Standard, Fast and two High-Speed I2C Interface Modes.The AD7994 normally remain in a shutdown state while not converting, and power up only for conversions.

This allows the widest dynamic input range to the ADC. On-chip limit registers can be programmed with high and low limits for the conversion result, and an open-drain, out-of-range indicator output (ALERT) becomes active when the programmed high or low limits are violated by the conversion result. This output can be used as an interrupt.PRODUCT HIGHLIGHTS 2 µs conversion time with low power consumption. I2C-compatible serial interface with pin-selectable addresses.
