General Description
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.

Features
♦ 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

Applications
    VCOM Adjustment for LCD Panels
    Backlight Adjustment
    LED Bias Adjustment
    Power-Supply Modules
    Fiber-Module Bias Setting
    Bias Setting for Radios
    Portable Consumer Electronics
