Analog Devices AD7398/AD7399 Quad DAC Datasheet Rev C
The AD7398/AD7399 family are quad voltage‑output digital‑to‑analog converters offering 12‑bit (AD7398) or 10‑bit (AD7399) resolution. They operate from a single 3 V‑5 V supply or a dual ±5 V supply and feature a 3‑wire SPI‑compatible serial interface, double‑buffered registers, and programmable power‑shutdown.
The document lists detailed electrical specifications, timing diagrams, absolute maximum ratings, pin‑out descriptions, and ordering information. It also includes typical performance curves, application notes for automotive and portable communications, and guidance for microprocessor interfacing.
