Working Principles

The MCP42050-E/SL operates by digitally controlling the resistance between its terminals. The digital control interface, powered by an external microcontroller or similar device, sends commands to adjust the wiper position within the potentiometer. This changes the effective resistance between the wiper terminal and the corresponding channel terminals, allowing precise control over the output voltage or current in a circuit.
