The terminal A pin is connected to the internal potenti-
ometer’s terminal A (available on some devices). The
potentiometer’s terminal A is the fixed connection to the
0x3F terminal of the digital potentiometer.
The terminal A pin is available on the MCP4011,
MCP4012 and MCP4013 devices. The terminal A pin
does not have a polarity relative to the terminal W or B
pins. The terminal A pin can support both positive and
negative current. The voltage on terminal A must be
between V
The terminal A pin is not available on the MCP4014.
The potentiometer’s terminal A is internally floating.

The terminal W pin is connected to the internal potenti-
ometer’s terminal W (the wiper). The wiper terminal is
the adjustable terminal of the digital potentiometer. The
terminal W pin does not have a polarity relative to
terminals A or B pins. The terminal W pin can support
both positive and negative current. The voltage on
terminal W must be between V
3.5
The terminal B pin is connected to the internal potenti-
ometer’s terminal B (available on some devices). The
potentiometer’s terminal B is the fixed connection to the
0x00 terminal of the digital potentiometer.
The terminal B pin is available on the MCP4011 device.
The terminal B pin does not have a polarity relative to
the terminal W or A pins. The terminal B pin can
support both positive and negative current. The voltage
on terminal B must be between V
The terminal B pin is not available on the MCP4012,
MCP4013 and MCP4014 devices.
For the MCP4013 and MCP4014, the internal potenti-
ometer’s terminal B is internally connected to V
Terminal B does not have a polarity relative to
terminals W or A. Terminal B can support both positive
and negative current.
For the MCP4012, terminal B is internally floating.
