While the device’s voltage is in the range of 1.8V ≤ V
< 2.7V, the Resistor Network’s electrical performance
of the device may not meet the data sheet
specifications.

3.3
The SCL pin is the serial clock pin of the I
The MCP401X acts only as a slave and the SCL pin
accepts only external serial clocks. The SCL pin is an
open-drain output. Refer to Section 5.0 “Serial
Interface - I
Interface communication.
3.4
The SDA pin is the serial data pin of the I
The SDA pin has a Schmitt trigger input and an
open-drain output. Refer to Section 5.0 “Serial
Interface - I
Interface communication.
3.5
The terminal B pin (available on some devices) is
connected to the internal potentiometer’s terminal B.
The potentiometer’s terminal B is the fixed connection
to the Zero Scale (0x00 tap) wiper value of the digital
potentiometer.
The terminal B pin is available on the MCP4017 device.
The terminal B pin does not have a polarity relative to
the terminal W pin. 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 MCP4018
and MCP4019 devices. For these devices, the
potentiometer’s terminal B is internally connected to
V
3.6
The terminal W pin is connected to the internal
potentiometer’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

The terminal A pin (available on some devices) is
connected to the internal potentiometer’s terminal A.
The potentiometer’s terminal A is the fixed connection
to the Full Scale (0x7F tap) wiper value of the digital
potentiometer.
The terminal A pin is available on the MCP4018
devices. The terminal A pin does not have a polarity
relative to the terminal W pin. 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 MCP4017
and MCP4019 devices. For these devices, the
potentiometer’s terminal A is internally floating.
