Overview
The AD7396AR, produced by Analog Devices Inc., is a dual, 12-bit voltage-output digital-to-analog converter (DAC) designed for low power consumption and single-supply operation. This device is part of the AD7396/AD7397 series, which offers pin-compatible 12-bit and 10-bit versions. The AD7396AR operates from a single supply voltage ranging from +2.7 V to +5.5 V, making it ideal for battery-operated applications. Built using a CBCMOS process, it provides low cost and ease of use in single-supply systems.
