CAT5271, CAT5273 Dual 256‐position I2C Compatible Digital Potentiometers (POTs) The CAT5271 and CAT5273 are dual 256-position digital programmable linear taper potentiometers ideally suited for replacing mechanical potentiometers and variable resistors.

The wiper settings are controlled through an I2C-compatible digital interface.

Upon power-up, the wiper assumes a midscale position and may be repositioned anytime after the power is stable.

The devices can be programmed to go to a shutdown state
