MCP41010 8 Bit Digital 10K Potentiometer with SPI Interface IC
The MCP41010 is a single-channel, 8-bit digital potentiometer (digipot) designed by Microchip Technology. It provides 256 discrete wiper positions for precise analog signal adjustment using a 10kΩ resistive network. The device is digitally controlled via an SPI-compatible serial interface, allowing microcontrollers and digital systems to adjust resistance electronically without mechanical wear or manual tuning.
This makes the MCP41010 ideal for replacing traditional mechanical potentiometers in applications requiring automatic calibration, remote control, or digital precision.
