Description
The MCP41XXX and MCP42XXX devices are 256-
position, digital potentiometers available in 10 k
,
50 k
and 100 k 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 A 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.
