MCP401X/2X Evaluation Board User’s Guide
2.2.1
Evaluating the MCP4021 and MCP4011
The MCP4021/11-XXXI/SN is an 8-pin digital potentiometer device with terminals A, B
and W available on the device pins. Footprint U1 supports the 150 mil SOIC package.
Resistors R2 and R3 are 2.5 k Ω on the populated PCB, along with the 10 k Ω
MCP4021-103I/SN digital potentiometer. This creates a “windowed” voltage divider
V wiper = ------------------------------------------- = ---------------------------------------------------------------------
R2 + R3 + R nom
EQUATION 2-1:
WINDOWED POTENTIOMETER – VOLTAGE DIVIDER
CALCULATION
V DD ? ( R wb + R3 ) 5.0V ? ( ( d ? 10k ) ? 63 + 2.5k )
2.5k + 2.5k + 10k
Where:
d = the wiper setting (0 to 63)

2.2.2
DO NOT populate U2 if using U1.
The MCP4011 has high-voltage tolerant pins and, therefore, accepts
high-voltage Increment and Decrement commands. Since this device is
nonvolatile, the WiperLock? Technology feature is not present.
Evaluating the MCP4022 and MCP4012
The MCP4022/12-XXXI/OT is a 6-pin, stand-alone digital rheostat with terminals A and
W available on the device pins. Footprint U2 supports the SOT-23-6 package. An
“INCR” command moves the wiper toward terminal A, thus causing the resistance
across the rheostat to decrease. A “DECR” command moves the wiper toward terminal
B, thus causing the resistance across the rheostat to increase.

3:
DO NOT populate U1 if using U2.
The included MCP4021 digital potentiometer samples could be used to
evaluate the MCP4022 simply by not populating R3 and letting terminal
B float.
The MCP4012 has high-voltage tolerant pins and, therefore, accepts
high-voltage Increment and Decrement commands. Since this device is
nonvolatile, the WiperLock? Technology feature is not present.
