The MAX5128 nonvolatile, single, linear-taper, digital
potentiometer performs the function of a mechanical
potentiometer, but replaces the mechanics with a simple
2-wire digital interface. The MAX5128 performs the
same function as a discrete potentiometer or variable
resistor and features 128 taps and 22kΩ end-to-end
resistance. The MAX5128 also features an ultra-small,
2mm x 2mm µDFN package and low 0.5µA (typ) standby
supply current, making this device ideal for portable
applications. The MAX5128 operates from a +2.7V to
+5.25V power supply. An integrated nonvolatile memory
recalls the programmed wiper position of the digital
potentiometer. A simple 2-wire up/down interface programs
the wiper position. The digital potentiometer provides
a low 5ppm/°C ratiometric temperature coefficient
and is specified over the extended -40°C to +85°C temperature
range.
