Description

The MCP41XXX and MCP42XXX devices are 256-

position, digital potentiometers available in 10 kΩ,

50 kΩ and 100 kΩ resistance versions. The

MCP41XXX is a single-channel device and is offered in

an 8-pin PDIP or SOIC package. The MCP42XXX con-

tains two independent channels in a 14-pin PDIP, SOIC

or TSSOP package. The wiper position of the

MCP41XXX/42XXX varies linearly and is controlled via

an industry-standard SPI interface. The devices con-

sume <1 µA during static operation. A software shut-

down feature is provided that disconnects the “A”

terminal from the resistor stack and simultaneously con-

nects 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 con-

tents 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. The

MCP42XXX SPI interface includes both the SI and SO

pins, allowing daisy-chaining of multiple devices. Chan-

nel-to-channel resistance matching on the MCP42XXX

varies by less than 1%. These devices operate from a

single 2.7 - 5.5V supply and are specified over the

extended and industrial temperature ranges.
