Overview
The AD5663BRMZ-1, produced by Analog Devices Inc., is a low power, dual 16-bit buffered voltage-out Digital-to-Analog Converter (DAC) that is part of the nanoDAC family. This device operates from a single supply voltage ranging from 2.7 V to 5.5 V 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 AD5663BRMZ-1 is ideal for portable, battery-operated equipment due to its low power consumption and power-down mode, which reduces current consumption significantly.
