Overview
The AD5324BRMZ-REEL7 is a quad-channel, 12-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This device features four buffered voltage output DACs, each with a resolution of 12 bits. The AD5324 is designed for low power consumption, making it suitable for portable battery-operated equipment. It operates from a single power supply ranging from 2.5 V to 5.5 V and includes on-chip rail-to-rail output buffer amplifiers. The device is controlled via a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols.
