Product Details

The MAX1668 evaluation system (EV system) consists of a MAX1668 evaluation kit (EV kit) and a companion Maxim system management bus (SMBus™) interface board.

The MAX1668 EV kit is an assembled and tested PC board that demonstrates the MAX1668 temperature sensor. It monitors the temperature of four external diode-connected transistors and one internal diode, and converts the temperatures to 8-bit, 2-wire serial data. Four 2N3906 temperature-sensor transistors come soldered to the board in SOT23 packages, but for more realistic experiments, any of the transistors can be removed and the board 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® SMBus 2-wire interface. Windows® 95/98/2000 compatible software provides a user-friendly interface to exercise the MAX1668 features. The program is menu driven and offers a graphic interface with control buttons and status display.

Order the MAX1668EVSYS for complete PC-based evaluation of the MAX1668. Order the MAX1668EVKIT if you already have an SMBus interface.
