Description
The MAX5487/MAX5488/MAX5489 dual, linear-taper, digital potentiometers function as mechanical potentiometers with a simple 3-wire SPI™-compatible digital interface that programs the wipers to any one of 256 tap positions. These digital potentiometers feature a nonvolatile memory (EEPROM) to return the wipers to their previously stored positions upon power-up.

The MAX5487 has an end-to-end resistance of 10kOhm, while the MAX5488 and MAX5489 have resistances of 50kOhm and 100kOhm, respectively. These devices have a low 35ppm/°C end-to-end temperature coefficient, and operate from a single +2.7V to +5.25V supply.

The MAX5487/MAX5488/MAX5489 are available in 16-pin 3mm x 3mm x 0.8mm thin QFN or 14-pin TSSOP packages. Each device is guaranteed over the extended -40°C to +85°C temperature range.

An evaluation kit is available:  MAX5488EVKIT
