Overview
The AD5327ARUZ is a quad 12-bit buffered voltage-output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device operates from a single 2.5 V to 5.5 V power supply and is housed in a 16-lead TSSOP package. It is designed for low power consumption, drawing 400 μA at 3 V, and features on-chip rail-to-rail output buffer amplifiers. The AD5327ARUZ is part of the AD5307/AD5317/AD5327 family, which offers versatile 3-wire serial interfaces compatible with SPI, QSPI, MICROWIRE, and DSP standards, operating at clock rates up to 30 MHz.
