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, non-
volatile, linear digital potentiometer communicating over
I
EEPROM used to store the potentiometer’s wiper posi-
tion for initialization during power-up. The EEPROM is
programmed through the I
face, communicating at data rates up to 400kbps. The
I
interface circuit using a computer or a user-supplied I
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
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 I
