The MCP41050-I/SN 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. 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
