Overview
The AD5304BRMZ-REEL7 is a quad 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This device is part of the AD5304/AD5314/AD5324 family, which includes DACs with resolutions of 8, 10, and 12 bits, respectively. The AD5304BRMZ-REEL7 operates from a single supply voltage ranging from 2.5 V to 5.5 V and features four buffered voltage output channels. Each channel includes an on-chip output amplifier that provides rail-to-rail output swing with a slew rate of 0.7 V/μs. The device is designed for low power consumption, making it suitable for portable battery-operated equipment.
