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.

Digital potentiometer applications can be divided into
two categories:
• Rheostat configuration
• Potentiometer (or voltage divider) configuration

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