MCP41010 Potentiometer: Circuit, Pinout, and Datasheet

MCP41010 is an integrated digital potentiometer produced by Microchip. It integrates a 10 kΩ digital potentiometer on a single chip. The wiper of the potentiometer has a total of 256 discrete adjustment nodes, and there is an 8 b E2PROM data register that directly controls the position of the wiper on the potentiometer. The user can write 8-bit words to the data register through corresponding instructions, and the adjustment accuracy can reach 256. The MCP41010 chip has an industry-standard SPI synchronous serial port, which can realize register operations to change the position of the sliding brush.

The wiper position of the MCP41010 varies linearly and is controlled via an industry-standard SPI interface. The devices consume <1 µA during static operation. A software shutdown feature is provided that disconnects the “A” terminal from the resistor stack and simultaneously connects the wiper to the “B” terminal. In addition, the dual During shutdown mode, the contents of the wiper register can be changed and the potentiometer returns from shutdown to the new value. The wiper is reset to the mid-scale position (80h) upon power-up. The RS (reset) pin implements a hardware reset and also returns the wiper to mid-scale.
