MCP41XXX/42XXX  
Single/Dual Digital Potentiometer with SPI™ Interface  
Features  
Description  
• 256 taps for each potentiometer  
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.  
• Potentiometer values for 10 kΩ, 50 kΩ and  
100 kΩ  
• Single and dual versions  
• SPI™ serial interface (mode 0,0 and 1,1)  
•
±1 LSB max INL & DNL  
• Low power CMOS technology  
• 1 µA maximum supply current in static operation  
• Multiple devices can be daisy-chained together  
(MCP42XXX only)  
• Shutdown feature open circuits of all resistors for  
maximum power savings  
• Hardware shutdown pin available on MCP42XXX  
only  
• Single supply operation (2.7V - 5.5V)  
• Industrial temperature range: -40°C to +85°C  
• Extended temperature range: -40°C to +125°C
