Overview
The AD7302BRUZ-REEL, produced by Analog Devices Inc., is a dual, 8-bit voltage output Digital-to-Analog Converter (DAC) designed for a wide range of applications. It operates from a single supply voltage of +2.7 V to +5.5 V, making it suitable for battery-powered and low-power devices. The AD7302 features on-chip precision output buffers that allow the DAC outputs to swing rail-to-rail, ensuring high accuracy and reliability. The device is available in a 20-lead TSSOP package and is lead-free and RoHS compliant.
