AD7903 PulSAR ADC

The AD7903 is a dual 16-bit, successive approximation, analogto-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 vo.
