Overview
The AD5678ARUZ-2REEL7 is a low-power, octal, buffered voltage-output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This device integrates four 12-bit DACs and four 16-bit DACs within a single package, making it highly versatile for various applications. It operates from a single supply voltage ranging from 2.7 V to 5.5 V and is guaranteed monotonic by design. The AD5678ARUZ-2REEL7 features an on-chip reference with an internal gain of 2, and it includes a power-on reset circuit and power-down mode to minimize current consumption.
