Digital Potentiometer Solutions
Single, Dual and Quad Potentiometer Options
Some devices offer multiple resistor networks on the same
device. Currently up to 4 resistor networks are available
on a single device. These resistor networks are referred to
as Pot 0 (Potentiometer 0), Pot 1, Pot 2 and Pot 3. Having
multiple potentiometers on the same device offers several
advantages, including:

Digital Potentiometer Design Guide
In some applications, the R
potentiometer is important for the application circuit. When
these potentiometers are on the same silicon, the R
resistance is small compared to the possible variation of
the R
devices with multiple resistor networks have R
specifications as well as additional information in the
characterization graph section.
The quad potentiometer devices are defined so that the
for the same leaded package type (such as TSSOP) the
Quad and Dual devices have a compatible footprint. The
following figure shows footprint compatibility for both the
MCP4261  MCP4361 and the MCP4262  MCP4362.
