AD7902 Analog to Digital Converter

Analog Devices Inc. AD7902 Analog to Digital Converters are a dual 16-bit, successive approximation 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−.
