32-Tap, Nonvolatile, Linear-Taper Digital  
Potentiometers in SOT23  
General Description  
Features  
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.

Recalled Upon Power-Up

5ppm/°C Ratiometric Temperature Coefficient  
32 Tap Positions  
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.  
Voltage-Divider or Variable-Resistor  
The MAX5471/MAX5474 have an end-to-end resistance  
of 50k, and the MAX5472/MAX5475 have an end-  
to-end resistance of 100k. 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.
