Overview
The AD5324ARMZ-REEL7 is a quad 12-bit buffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD5324 series, which operates from a single supply voltage ranging from 2.5 V to 5.5 V. It is housed in a 10-lead MSOP package and is designed for low power consumption, making it suitable for portable battery-operated equipment.
The device features four on-chip output buffer amplifiers, each providing rail-to-rail output swing with a slew rate of 0.7 V/μs. The DACs are controlled via a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, allowing for high-speed data transfer up to 30 MHz.
