Overview
The AD5325BRMZ from Analog Devices Inc. is a quad 12-bit buffered voltage output Digital-to-Analog Converter (DAC) packaged in a 10-lead MSOP. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes 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 low power consumption and high precision.
