Description
256-Position I2C Compatible Digital Potentiometer
The CAT5171 is a 256−position digitally programmable 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.
