Overview
The AD5664ARMZ-REEL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a low power, quad, 16-bit buffered voltage-out digital-to-analog converter (DAC) that operates from a single 2.7 V to 5.5 V supply. This device is designed to be highly efficient, making it ideal for portable battery-operated equipment. The AD5664ARMZ-REEL7 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, with software-selectable output loads in power-down mode.
