Overview
The AD5325BRM-REEL is a quad 12-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is designed for low power operation and features a 2-wire (I2C-compatible) serial interface. It is packaged in a 10-lead MSOP and is suitable for a wide range of applications requiring precise analog voltage output.
The AD5325BRM-REEL operates from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V and 600 μA at 5 V. It includes on-chip rail-to-rail output buffer amplifiers and supports simultaneous update of outputs through the LDAC function. The device also features power-on reset to 0 V and three power-down modes, reducing current to as low as 80 nA at 3 V and 200 nA at 5 V.
