Overview
The AD5663BRMZ-REEL7, produced by Analog Devices Inc., is a dual 16-bit buffered voltage-out Digital-to-Analog Converter (DAC) that operates from a single 2.7 V to 5.5 V supply. This component is part of the *nano*DAC® family and is known for its low power consumption, making it ideal for portable, battery-operated equipment. The AD5663 features a power-on reset circuit that ensures the DAC output powers up to 0 V or midscale 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.
