Buy Now View Details

Features and Benefits

  • Power-On Recall of Wiper Position from Nonvolatile Memory
  • 2.7V to 5.25V Single-Supply Operation
  • Selectable Device Address Input
  • I²C-Compatible Serial Interface
  • Easy-to-Use Menu-Driven Software
  • Include Windows 98-/2000-/XP-Compatible Software and Demo PC Board
  • Evaluate the MAX5417/MAX5418/MAX5419
  • Assembled and Tested

Product Details

The MAX5417L evaluation system (EV system) consists of a MAX5417L evaluation kit (EV kit) and a companion command module interface board (CMODUSB).

The MAX5417L EV kit is an assembled and tested PC board that features the MAX5417L 50kΩ, linear-taper digital potentiometer. The MAX5417L IC features an internal nonvolatile EEPROM used to store the potentiometer's wiper position for initialization during power-up. The EEPROM is programmed through the I²C-compatible serial interface, transmitting at rates up to 400kbps. The MAX5417L is programmed with a factory-preset address and features an address input for a total of two unique address combinations. The MAX5417L EV kit can also be used to evaluate other versions of the MAX5417, MAX5418 (100kΩ), and MAX5419 (200kΩ) digital potentiometers.

The EV kit also includes Windows® 98-/2000-/XP-compatible software that provides a professional user interface for exercising the MAX5417L's features. The program is menu-driven and offers a graphical user interface (GUI) complete with control buttons and a track bar.

The CMODUSB command module allows a personal computer (PC) to use its USB port to emulate an I²C 2-wire interface. Order the MAX5417LEVCMODU for a complete PC-based EV kit. Order the MAX5417LEVKIT if a CMODUSB command module or an I²C-compatible 2-wire interface system has already been purchased with a Maxim EV system.

Applications

  • Liquid-Crystal Display (LCD) Contrast Control
  • Low-Drift Programmable-Gain Amplifiers
  • Mechanical Potentiometer Replacements
  • Volume Control
