The MAX5478 evaluation system (EV system) consists
of a MAX5478 evaluation kit (EV kit) and a companion
command module interface board (CMODUSB).
The MAX5478 EV kit is an assembled and tested PC
board that features the MAX5478 50kΩ linear-taper
dual digital potentiometer. The MAX5478 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 MAX5478 address can be programmed
by configuring three input pins for a total of
eight unique address combinations. The MAX5478 EV
kit can also be used to evaluate the MAX5477 (10kΩ)
or the MAX5479 (100kΩ) dual digital potentiometers.
The EV kit also includes Windows® 98-/2000-/XP-compatible
software that provides a professional user interface
for exercising the MAX5478's features. The program is
menu-driven and offers a graphical user interface (GUI)
complete with control buttons and track bars.
The CMODUSB command module allows a personal
computer (PC) to use its USB port to emulate an I²C 2-wire interface. Order the MAX5478EVCMODU for a
complete PC-based EV kit. Order the MAX5478EVKIT if
a CMODUSB command module or an I²C-compatible
2-wire interface system has already been purchased
with a Maxim EV system.
* Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", "-" in the part number suffix describes RoHS status. Package drawings may show a different suffix character.
