AD7903BRQZ-RL7

Dual Differential 16-Bit, 1 MSPS PulSAR ADC 12.0 mW in QSOP. The AD7903 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 AD7903 samples the voltage difference between the INx+ and INx− pins. The voltages on these pins usually swing in opposite phases between 0 V and V_REF. The externally applied reference voltage of the REFx pins (V_REF) can be set independently from the supply voltage pins, VDDx. The power of the device scales linearly with throughput.
