Overview
The CAT5113VI-10-GT3 is a digital potentiometer produced by onsemi, designed as an electronic replacement for mechanical potentiometers. This component 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 CAT5113 contains a 100-tap series resistor array connected between two terminals, RH and RL, with the wiper terminal RW. The device is controlled by three input pins: CS (Chip Select), U/D (Up/Down), and INC (Increment). The wiper setting is stored in nonvolatile memory, ensuring that the setting is retained even when the device is powered down and automatically reinstated when power is restored.
