5.3
The CS pin is High-Voltage (V
MCP402X. This allows the MCP401X to be used in
MCP402X applications without needing to change
other portions of the application circuit.
6.0
Digital potentiometer applications can be divided into
two categories:
• Rheostat configuration
• Potentiometer (or voltage divider) configuration
Figure 6-1 shows a block diagram for the MCP401X
resistors.

That is, each tap selection resistance
has a small variation. This variation
effects the smaller resistance devices

R
typical step resistances for each device.
The total resistance of the device has minimal variation
due to operating voltage (see Figure 2-11, Figure 2-24,
Figure 2-36 or Figure 2-48).

Terminal A and B, as well as the wiper W, do not have
a polarity. These terminals can support both positive
and negative current.
