Overview
The AD7683BRMZ is a 16-bit, charge redistribution, successive approximation, PulSAR® analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC operates from a single power supply, VDD, ranging from 2.7 V to 5.5 V. It features a low power, high speed, 16-bit sampling ADC with no missing codes (B grade), an internal conversion clock, and a serial, SPI-compatible interface port. The device also includes a low noise, wide bandwidth, short aperture delay, track-and-hold circuit, making it ideal for multiple, multiplexed channel applications.
