Overview
The AD5668BRUZ-3 is a 16-bit, octal, buffered voltage-output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device operates from a single 2.7 V to 5.5 V supply and is designed for high precision and low power consumption. It features an on-chip reference with an internal gain of 2, providing a full-scale output range of 2.5 V or 5 V depending on the reference configuration. The AD5668BRUZ-3 is part of the denseDAC family and is known for its high resolution, fast settling time, and versatile serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.
