Product Overview

The MCP42010-I/P is a Digital Potentiometer with SPI™ interface. The wiper position of the potentiometer varies linearly and is controlled via an industry-standard SPI interface. It consumes <1µA 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 MCP42XXX has a SHDN pin that performs the same function in hardware. 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. Its SPI interface includes both the SI and SO pins, allowing daisy-chaining of multiple devices. Channel-to-channel resistance matching on the potentiometer varies by less than 1%.
  • Low power CMOS technology
  • Shutdown feature open circuits of all resistors for maximum power savings
  • ±1 LSB Maximum INL and DNL
  • 1µA Maximum supply current in static operation
