Overview
The AD7682BCBZ-RL7 is a 16-bit, 4-channel analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the PulSAR (Pulse Code Modulation Successive Approximation Register) family and is designed for low power, multichannel data acquisition systems. It operates from a single power supply and includes a true 16-bit SAR ADC, a low crosstalk multiplexer, an internal low drift reference, a temperature sensor, and a selectable one-pole filter. The AD7682 uses a simple serial port interface (SPI) for configuration and data transfer, with power dissipation scaling with throughput.
