MCP41010 IC – 8-Bit Digital 10K Potentiometer with SPI Interface IC

The MCP41010 and devices are 256- position, digital potentiometers available in 10 k?, 50 k? and 100 k? resistance versions. The MCP41010 is a single-channel device and is offered in an 8-pin PDIP or SOIC package. The wiper position of the MCP41010 varies linearly and is controlled via an industry-standard SPI interface. The devices consume <1 ?A 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. 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.
