MAX5128ELA+T Digital Potentiometer ICs 128 Tap Nonvolatile Linear Taper Digital A1221LLHLT-T DS28EC20+ Semiconductors
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. 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
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
