Overview
The AD5325BRMZ-REEL7 is a quad 12-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component operates from a single 2.5 V to 5.5 V supply and is designed for low power consumption, making it suitable for portable battery-operated equipment. The AD5325 features a 2-wire serial interface compatible with I²C and SMBus protocols, allowing for high-speed data transfer up to 400 kHz. The device includes on-chip output amplifiers that provide rail-to-rail output swing and a slew rate of 0.7 V/μs. It is packaged in a 10-lead MSOP, which is lead-free and RoHS compliant.
