Overview
The AD5324ARM-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 2.5 V to 5.5 V power supply and is designed for low power consumption, making it suitable for portable battery-operated equipment. The device features four buffered DACs, each with on-chip rail-to-rail output buffer amplifiers, and a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.
