Product Summary

The MAX5471EZT-T is a linear-taper digital potentiometer. It functions 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 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. 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.
