MAX6698 Evaluation Kit/Evaluation System Evaluate MAX6698 The MAX6698 evaluation kit EV kit and evaluation system is an assembled and tested PC board with a mounted MAX6698. The EV kit allows full evaluation of the MAX6698 seven-channel temperature sensor. The MAX6698 monitors its own die temperature, the junction temperatures of three external diode-connected transistors, and the temperatures of three thermistors. It converts the temperature to 8-bit or 11-bit for remote channel 1 2-wire serial data that can be accessed over a 2wire serial bus. Refer to the MAX6698 data sheet for additional information. The MAX6698 EV kit includes external diode-connected transistors and thermistors soldered to the board, which can be removed. The board can then be connected through a twisted pair to remote diodes and thermistors close to your system. The MAX6698 evaluation system consists of a Maxim command module CMOD232 and a MAX6698 EV kit. The CMOD232 board connects to a computer’s RS-232 serial port to provide a computer controlled SMBus /I2C bus. 95/98/2000/XP-compatible software provides a user-friendly interface to exercise the features of the MAX6698. The program is menu driven and offers a graphic interface with control buttons and status display. Order the MAX6698EVCMOD2 for complete PC-based evaluation of the MAX6698. Order the MAX6698EVKIT if you already have a CMOD232 SMBus interface.
