CAT5172 256-position SPI Compatible Digital Potentiometer

CAT5172 256‐position SPI Compatible Digital Potentiometer (POT) The CAT5172 is a 256-position digital linear taper potentiometer ideally suited for replacing mechanical potentiometers and variable resistors. Like mechanical potentiometers, the CAT5172 has a resistive element, which can span VCC to Ground or float anywhere between the power supply rails. Wiper settings are controlled through an SPI-compatible digital interface. Upon power-up, the wiper assumes a mid-span position and may be repo.
