Overview
The AD7916BCPZ-RL7 is a 16-bit, successive approximation, analog-to-digital converter (ADC) produced by Analog Devices Inc. This high-performance ADC operates from a single power supply, VDD, and features a low power, high speed, 16-bit sampling ADC along with a versatile serial interface port. The device is designed to sample the voltage difference between the IN+ and IN− pins, with voltages typically swinging in opposite phases between 0 V and VREF. The reference voltage, REF, is applied externally and can be set independently of the supply voltage, VDD.
