CS High Voltage
The CS pin is High-Voltage (VIHH) tolerant, like the
MCP402X. This allows the MCP401X to be used in
MCP402X applications without needing to change
other portions of the application circuit.

RESISTOR
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.
FIGURE 6-1:
Resistor Block Diagram.
Step resistance (RS) is the resistance from one tap
setting to the next. This value will be dependent on the
RAB value that has been selected. Table 6-1 shows the
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,
TABLE 6-1: TYPICAL STEP RESISTANCES
Terminal A and B, as well as the wiper W, do not have
a polarity. These terminals can support both positive
and negative current.

Note 1: The wiper resistance is tap dependent.
That is, each tap selection resistance
has a small variation. This variation
effects the smaller resistance devices

Ω) more.
