Overview
The CAT5113ZI-10-T3 is a digital potentiometer (POT) produced by onsemi. This component is designed as an electronic replacement for mechanical potentiometers, offering 100-position linear taper potentiometer functionality. It is ideal for automated adjustments in high-volume production lines and applications where periodic adjustments are necessary but difficult to access or located in hazardous or remote environments.
The device features a 100-tap series resistor array connected between two terminals, RH and RL, with a wiper terminal RW that can be controlled by three input pins: INC, U/D, and CS. The wiper setting is stored in nonvolatile memory, ensuring that the setting is retained even when the device is powered down and reinstated when power is restored.
