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
- Backlight Adjustment
- Bias Setting for Radios
- Fiber-Module Bias Setting

Evaluation Kits 2
MAX5128EVKIT+
Evaluation Kit/Evaluation System for the MAX5128
Product Detail
The MAX5128 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed-circuit board (PCB) that evaluates the MAX5128 22kΩ, linear-taper digital potentiometer. The EV kit provides both a mechanical pushbutton-controlled interface and a microprocessor-controlled interface.
The MAX5128 evaluation system (EV system) consists of the MAX5128 EV kit and the Maxim CMAXQUSB+ command module. The EV kit includes Windows® 98SE/2000/XP-compatible software that provides a professional user interface for exercising the MAX5128's features. The program is menu driven and offers a graphical user interface (GUI) complete with control buttons and a track bar.
Order the complete EV system (MAX5128EVCMAXQU+) for comprehensive evaluation of the MAX5128 using a PC. Order just the EV kit (MAX5128EVKIT+) if the CMAXQUSB+ module has already been purchased with a previous Maxim EV system.
Applications
- Backlight Adjustment
- Bias Setting for Radios
- Fiber-Module Bias Setting
- LED Bias Adjustment
- Portable Consumer Electronics
- Power-Supply Modules
- VCOM Adjustment for LCD Panels
