Product Description

The AD7902BRQZ is a dual pseudo differential 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 ADC and a versatile serial port interface. On the CNVx rising edge, the converter samples an analog input IN+, in the range of 0V to VREF with respect to a ground sense IN-. The externally applied reference voltage of the REFx pins 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.
16-bit resolution with no missing codes
