Overview
The AD5347BRUZ is a 10-bit octal digital-to-analog converter (DAC) produced by Analog Devices Inc. This device operates from a supply voltage range of 2.5 V to 5.5 V and features a parallel interface for data input. It is designed to provide high accuracy and reliability, making it suitable for a variety of applications. The AD5347BRUZ includes on-chip output buffers that can drive the output to both supply rails and offers a choice between buffered or unbuffered reference inputs. The device also includes features such as simultaneous update of DAC outputs, asynchronous CLR facility, and power-on reset to 0 V.
