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 MCP4021,
MCP4022 and MCP4023 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 teminal A must be
between V
The terminal A pin is not available on the MCP4024.
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
teminal 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 MCP4021 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 teminal B must be between V
The terminal B pin is not available on the MCP4022,
MCP4023 and MCP4024 devices.
For the MCP4023 and MCP4024, 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 MCP4022, terminal B is internally floating.
