32-Tap, Nonvolatile, Linear-Taper Digital
Potentiometers in SOT23
General Description
The MAX5471/MAX5472/MAX5474/MAX5475 linear-
taper digital potentiometers function as mechanical
potentiometers, but replace the mechanics with a sim-
ple 3-wire up/down digital interface. These digital
potentiometers feature nonvolatile memory (EEPROM)
to return the wiper to its previously stored position upon
power-up.
The MAX5471/MAX5472 are 2-terminal, variable resistors
in 6-pin SOT23 packages. The MAX5474/MAX5475 are
3-terminal potentiometers in 8-pin SOT23 packages.
The MAX5471/MAX5474 have an end-to-end resistance
of 50kΩ, and the MAX5472/MAX5475 have an end-
to-end resistance of 100kΩ. All of these devices have
32 wiper positions, a low ratiometric temperature coeffi-
cient (5ppm/°C), and all operate from a single +2.7V to
+5.25V supply. Each device is guaranteed over the
extended -40°C to +85°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
