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.
