The AD7376 is one of the few high voltage, high performance digital potentiometers on the market. This device can be used as a programmable resistor or resistor divider. With digital rather than manual control, the AD7376 provides layout flexibility and allows closed-loop dynamic controllability.
The AD7376 is a 128‑position digital potentiometer available in 10 kΩ, 50 kΩ, and 100 kΩ resistance options. It operates from 5 V to 30 V single‑supply or +5 V to +15 V dual‑supply and features a 3‑wire SPI‑compatible serial interface with a shutdown current of less than 1 pA.
The device is offered in 14‑lead TSSOP and 16‑lead SOIC packages and is rated for an industrial temperature range of –40 °C to +85 °C. Detailed electrical characteristics, timing specifications, pin configurations, and ordering information are provided.
