Digital Potentiometer Design Guide
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:
■ Cost per potentiometer
■ PCB layout area per potentiometer
■ Variation between potentiometers
Digital Potentiometer Solutions
In some applications, the RAB resistance variation between
potentiometer is important for the application circuit. When
these potentiometers are on the same silicon, the RAB
resistance is small compared to the possible variation of
the RAB resistance on different devices. The data sheets for
devices with multiple resistor networks have RAB matching
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.
