The AD5398 is a single 10-bit DAC with 120 mA output current sink capability. It features an internal reference and operates from a single 2.7 V to 5.5 V supply. The DAC is controlled via a 2-wire (I2C-compatible) serial interface that operates at clock rates up to 400 kHz. The AD5398 incorporates a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write takes place.
The AD5398 is a single‑channel 10‑bit digital‑to‑analog converter offering up to 120 mA of current‑sink capability. It operates from a 2.7 V to 5.5 V supply and includes an internal reference, power‑on reset and power‑down functions.
Designed for consumer camera applications such as autofocus and image stabilization, it is also suitable for industrial control of heaters, fans, solenoids and other loads across a –40 °C to +85 °C temperature range.
