Overview
The AD5663BRMZ-1REEL7, produced by Analog Devices Inc., is a low-power, dual 16-bit buffered voltage-out digital-to-analog converter (DAC). This component is part of the *nano*DAC® family and is designed to operate from a single 2.7 V to 5.5 V supply. It 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. The AD5663BRMZ-1REEL7 is particularly suited for portable, battery-operated equipment due to its low power consumption, which is typically 0.6 mW at 3 V and 1.25 mW at 5 V. The device also includes a power-down feature that reduces current consumption to 480 nA at 5 V, making it highly efficient in various applications.
