The MAX6681 evaluation system (EV system) consists of a MAX6681 evaluation kit (EV kit) and a companion Maxim system management bus (SMBus™) 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-connected transistor (a 2N3906 transistor) soldered to the board, but removable. The board can then be connected 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® 95/98/2000-compatible software provides a user-friendly interface to exercise the features of the MAX6681. The program is menu driven and offers a graphic interface 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.
