MAX5432 Evaluation Kit

General Description

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, 50k Ω , non-

volatile, linear digital potentiometer communicating over

I 2 C. The MAX5432 features an internal nonvolatile

EEPROM used to store the potentiometer’s wiper posi-

tion for initialization during power-up. The EEPROM is

programmed through the I 2 C-compatible serial inter-

face, communicating at data rates up to 400kbps. The

I 2 C signals can be transmitted through an on-board USB

interface circuit using a computer or a user-supplied I 2 C

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 I 2 C

addresses. The MAX5432 EV kit is shipped with a

MAX5432LETA IC installed.
