128-Tap, Nonvolatile, Linear-Taper Digital

Potentiometer in 2mm x 2mm µDFN Package

General Description

Features

The MAX5128 nonvolatile, single, linear-taper, digital

potentiometer performs the function of a mechanical

potentiometer, but replaces the mechanics with a sim-

ple 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) stand-

by supply current, making this device ideal for portable

applications. The MAX5128 operates from a +2.7V to

+5.25V power supply. An integrated nonvolatile memo-

ry recalls the programmed wiper position of the digital

potentiometer. A simple 2-wire up/down interface pro-

grams the wiper position. The digital potentiometer pro-

vides a low 5ppm/°C ratiometric temperature coefficient

and is specified over the extended -40°C to +85°C tem-

perature range.

♦ Ultra-Small, 2mm x 2mm, 8-Pin µDFN Package

♦ Power-On Recall of Wiper Position from

Nonvolatile Memory

♦ 22kΩ End-to-End Resistance

♦ 128 Tap Positions

♦ 5ppm/°C Ratiometric Temperature Coefficient

♦ 1.5µA (max) Standby Supply Current

♦ +2.7V to +5.25V Single Supply Operation

♦ 80,000 Wiper Store Cycles

♦ 50-Year Wiper Data Retention
