Analog Devices AD7390ARZ Digital-to-Analog Converter

AD7390ARZ is a 12-bit voltage‑output digital‑to‑analog converter from Analog Devices, housed in an 8‑lead SOIC package and designed for single‑supply operation around 3 V. It uses a serial input interface (three‑wire serial input) and is specified to operate from 2.7 V to 5.5 V, making it suitable for compact, battery‑powered designs. The device provides a buffered voltage output (VOUT) with a rail‑to‑rail REFIN to DACOUT reference path, enabling full‑scale output that can match the supply or a user‑defined reference. Power consumption is listed as under 100 µA, and the AD7390/AD7391 family comprises 10‑ and 12‑bit DAC options, with the AD7390 representing the 12‑bit member of the family.
