Overview
CAT5171 256‐position I2C Compatible Digital Potentiometer (POT) The CA5171 is a 256-position digital linear taper potentiometer 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 device can be programmed to reset the wiper position to midscale or to go to a shutdown state during operation.
An address input pin, AD0, allows the connection of two devices onto the same I2C bus.
The CAT5171 operates from 2.
7 V to 5.
5 V, while consuming less than 2 mA.
This low operating curren...
