Overview
The AD5663ARMZ-REEL7, produced by Analog Devices Inc., is a low power, dual 16-bit buffered voltage-out Digital-to-Analog Converter (DAC) that belongs to the nanoDAC® family. This device operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. It features a versatile 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, operating at clock rates up to 50 MHz. The AD5663 is particularly suited for portable, battery-operated equipment due to its low power consumption and power-down mode capabilities.
