Evaluation Kit for the MAX5432 and MAX5433

Active: In Production.

The MAX5432 evaluation kit (EV kit) is an assembled and tested printed-circuit board (PCB) that evaluates the MAX5432 IC. The MAX5432 is a 32-tap, 50kΩ, nonvolatile, linear digital potentiometer communicating over I²C. The MAX5432 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, communicating at data rates up to 400kbps. The I²C signals can be transmitted through an on-board USB interface circuit using a computer or a user-supplied I²C bus along with the PCB interfacing pads.

The EV kit also features Windows 2000/XP/Vista®-compatible software that provides a professional user interface for exercising the MAX5432's features. The program is menu driven and offers a graphical user interface (GUI) complete with buttons, track bars, and pulldown menus.

The EV kit is powered from a 3.3V source generated from the EV kit's USB interface circuit, or an external 2.7V to 5.25V DC power supply. The MAX5432 IC is available in two versions, the MAX5432LETA and the MAX5432META; each version has two selectable I²C addresses. The MAX5432 EV kit is shipped with a MAX5432LETA IC installed.

The EV kit can also evaluate the MAX5433 (100kΩ) after IC replacement (U1). The MAX5433 is also available in two versions; each version has four unique I²C addresses.
