Overview
The AD5304BRMZ-REEL is a quad 8-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5304 series, which includes 8-, 10-, and 12-bit versions. The AD5304BRMZ-REEL operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes 500 μA at 3 V. It features a 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, allowing for clock rates up to 30 MHz. The device includes on-chip output amplifiers that provide rail-to-rail output swing with a slew rate of 0.7 V/μs. The DACs share a single reference input pin and include programmable power-down modes for energy efficiency.
