Overview
The AD7983BRMZ-RL7 is a 16-bit, successive approximation, analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single power supply and features a high-speed, low-power sampling ADC along with a versatile serial interface port. It is designed to sample an analog input between 0 V and the external reference voltage, REF, with respect to a ground sense IN−. The device is compatible with various logic levels (1.8 V, 2.5 V, 3 V, or 5 V) using a separate supply VIO.
