Overview
The AD5325BRMZ-REEL, produced by Analog Devices Inc., is a quad 12-bit buffered voltage output Digital-to-Analog Converter (DAC) packaged in a 10-lead MicroSOIC (MSOP). This device operates from a single 2.5 V to 5.5 V supply, consuming a low current of 500 μA at 3 V. It features a 2-wire serial interface compatible with I²C and SMBus protocols, allowing for clock rates up to 400 kHz. The AD5325 is designed for applications requiring multiple DAC channels with precise voltage output and low power consumption.
