Overview
The CAT5114VI-50-GT3 is a single digital potentiometer (POT) produced by onsemi, designed as an electronic replacement for mechanical potentiometers and trim pots. This component is ideal for automated adjustments on high-volume production lines and is well-suited for applications where equipment requiring periodic adjustment is difficult to access or located in hazardous or remote environments. The CAT5114 features a 32-tap series resistor array connected between two terminals, RH and RL, with a wiper terminal RW that can be controlled via three input pins: CS, U/D, and INC. The wiper setting is stored in nonvolatile memory, ensuring that it is not lost when the device is powered down and is automatically reinstated when power is restored.
