MAX6681 Evaluation System/Evaluation Kit
General Description
The MAX6681 evaluation system (EV system) consists of a
MAX6681 evaluation kit (EV kit) and a companion Maxim
system management bus (SMBus)鈩?interface board.
The MAX6681 EV kit is an assembled and tested PC
board that demonstrates the MAX6681 temperature
sensor. The MAX6681 monitors its temperature and the
junction temperature of an external diode-connected
transistor. It converts the temperature to 8-bit or 11-bit
2-wire serial data. (Note: 11-bit resolution is for the
external sensor only.)
The MAX6681 EV kit includes the external diode-con-
nected transistor (a 2N3906 transistor) soldered to the
board, but removable. The board can then be connect-
ed through a twisted pair to a remote diode close to
your system.
The Maxim SMBus interface board (MAXSMBUS)
allows an IBM-compatible PC to use its parallel port to
emulate an Intel SMBus 2-wire interface. Windows庐
95/98/2000-compatible software provides a user-friend-
ly interface to exercise the features of the MAX6681.
The program is menu driven and offers a graphic inter-
face with control buttons and status display. (Note:
Windows 2000 requires the installation of a driver; refer
to Win2000.pdf or Win2000.txt located on the diskette.)
Order the MAX6681EVSYS for a complete IBM
PC-based evaluation of the MAX6681. Order the
MAX6681EVKIT if you already have an SMBus interface.
