Overview
The CAT5113VI-01-GT3 is a single digital potentiometer (POT) designed by onsemi as an electronic replacement for mechanical potentiometers. It is ideal for automated adjustments in 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 device features a 100-tap series resistor array and is controlled by three input pins: CS (Chip Select), U/D (Up/Down), and INC (Increment). The wiper setting is stored in non-volatile memory, ensuring that the setting is retained even when the device is powered down and automatically recalled when power is restored.
