Overview
The AD5664BRMZ-REEL7, part of the nanoDAC® family from Analog Devices Inc., is a low-power, quad, 16-bit buffered voltage-out digital-to-analog converter (DAC). This device operates from a single supply voltage ranging from 2.7 V to 5.5 V, making it suitable for a variety of applications, including portable battery-operated equipment. The AD5664 features a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. It also includes a power-down feature that significantly reduces current consumption to 480 nA at 5 V, enhancing its energy efficiency.
