AD5398A is a 120mA, 10-bit, I2C DAC that is used in consumer and industrial applications.
The AD5398A is a single‑chip 10‑bit digital‑to‑analog converter featuring a 120 mA current‑sink output and an internal reference. 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 up to 400 kHz clock rates. The device includes power‑on reset, power‑down function (0.5 µA typical), and guaranteed monotonicity over all codes.
Designed for consumer lens autofocus, image stabilization, optical zoom, and a range of industrial applications such as heater, fan, and valve control, the AD5398A provides low‑noise performance and a wide temperature range (‑30 °C to +85 °C). Key specifications include 10‑bit resolution, 120 mA maximum sink current, and a 0.6 VDD output compliance.
