Overview
The AD7399BRZ-REEL is a quad, 10-bit, voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD7398/AD7399 family, which is designed to operate from a single 3 V to 5 V supply or a dual ±5 V supply. Built using the robust CBCMOS process, these monolithic DACs offer low cost and ease of use in single or dual-supply systems. The AD7399 is particularly suited for applications requiring multiple DAC channels with high precision and reliability.
