Overview
The AD7983BCPZ-RL is a 16-bit, successive approximation, analog-to-digital converter (ADC) produced by Analog Devices Inc. This component 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 ADC samples an analog input between 0 V to an externally applied reference voltage (REF) with respect to a ground sense. It is designed for applications requiring high precision and speed, with compatibility across various logic levels (1.8 V, 2.5 V, 3 V, or 5 V) using a separate supply VIO.
