Analog Devices AD5821 Datasheet
The AD5821 is a 10‑bit digital‑to‑analog converter capable of sinking up to 120 mA. It operates from a single 2.7 V to 5.5 V supply and is controlled via a 2‑wire I²C‑compatible serial interface that supports clock rates up to 400 kHz. The device includes an internal reference, power‑down function, and guaranteed monotonicity over all codes.
Designed for consumer camera applications such as lens autofocus, image stabilization, and optical zoom, the AD5821 is also suitable for industrial uses including heater, fan, cooler, solenoid, valve, and light control. The datasheet details electrical specifications, timing diagrams, pin assignments, and mechanical dimensions for board integration.
