Product Introduction

Overview

The AD7302BRUZ-REEL7 is a dual, 8-bit voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component operates from a single supply voltage ranging from +2.7V to +5.5V. It features on-chip precision output buffers that allow the DAC outputs to swing rail-to-rail, making it suitable for a variety of applications requiring precise voltage control. The AD7302 has a parallel microprocessor and DSP-compatible interface with high-speed registers and double-buffered interface logic, enabling efficient data transfer and control.
