The MAX6655 evaluation system (EV system) consists
of a MAX6655 evaluation kit (EV kit) and a companion
Maxim SMBus™ interface board.
The MAX6655 EV kit is an assembled and tested PC
board that demonstrates the MAX6655 dual
remote/local temperature sensor and four-channel volt-
age monitor. It monitors the MAX6655 temperature and
supply voltage, the temperature of two external diode-
connected transistors, and the voltage of three external
supplies. Temperature is converted to 11-bit serial data
and voltage to 8-bit data. Two 2N3906 temperature-
sensor transistors come soldered to the board in
SOT23 packages, but they can be removed. The board
can then be connected through a twisted pair to remote
diodes closer to your system.
The Maxim SMBus interface board (MAXSMBUS)
allows an IBM-compatible PC to use its parallel port to
emulate an Intel System Management Bus (SMBus) 2-
wire interface. Windows® 95/98-compatible software
provides a user-friendly interface to exercise the fea-
tures of the MAX6655. The program is menu driven and
offers a graphic interface with control buttons and sta-
tus display.
Order the MAX6655EVSYS for complete IBM PC-based
evaluation of the MAX6655. Order the MAX6655EVKIT if
you already have an SMBus interface.
To evaluate the MAX6656, order a free sample of the
MAX6656MEE.
