CAT5172/D
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 repositioned anytime after the power is stable.
The CAT5172 operates from 2.7 V to 5.5 V, while consuming less
than 2
mA. This low operating current, combined with a small package
footprint, make the CAT5172 ideal for battery-powered portable
appliance.
