Overview
The CAT5113VI-00-GT3 is a single digital potentiometer (POT) designed by onsemi as an electronic replacement for mechanical potentiometers. It is ideal for automated adjustments on high-volume production lines and is well-suited for applications where equipment requiring periodic adjustment is either difficult to access or located in hazardous or remote environments.
This device features a 100-tap series resistor array connected between two terminals, RH and RL, with an up/down counter and decoder controlled by three input pins (CS, U/D, and INC) that determine the wiper position. The wiper setting is stored in nonvolatile memory, ensuring it is not lost when the device is powered down and is automatically reinstated when power is restored.
