Working Principles

The MCP4241T-104E/SL operates by digitally controlling the resistance between its terminal A and terminal B. The wiper terminal, connected to the internal resistive network, can be adjusted to any position within the specified resistance range. This adjustment is achieved through the SPI interface, which communicates with the potentiometer's non-volatile memory. The programmed resistance value is stored in the memory and remains unchanged even after power is removed.
