The AD7902 is a dual 16-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDDx, per ADC. It contains two low power, high speed, 16-bit sampling ADCs and a versatile serial port interface (SPI). On the CNVx rising edge, the AD7902 samples an analog input, ?IN+ in the range of 0 V to VREF with respect to a ground sense, IN?. The externally applied reference voltage of the REFx pins (VREF) can be set independently from the supply voltage pins, VDDx. The power of the device scales linearly with throughput.Using the SDIx inputs, the SPI-compatible serial interface can also daisy-chain multiple ADCs on a single 3-wire bus and provide an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate VIOx supplies.The AD7902 is available in a 20-lead QSOP package with operation specified from ?40?C to +125?C.APPLICATIONS Battery-powered equipment Communications Automated test equipment (ATE) Data acquisition Medical instrumentation Redundant measurement Simultaneous sampling
