The MAX6675 evaluation kit (EV kit) is an assembled
and tested printed circuit board (PCB) that demon-
strates the MAX6675 thermocouple digital temperature
sensor. It accepts the input from a type-K thermocouple
and converts the temperature to 12-bit data.
The MAX6675 EV kit connects to a computer for
acquiring the data from the MAX6675. Windows
95/98/2000/XP compatible software provides a user-
friendly interface to display the 12-bit data and convert
it to a temperature.
The EV kit includes a type-K thermocouple for evalua-
tion up to +80°C.
To evaluate the MAX6674, order a free sample of the
MAX6674ISA.

DESCRIPTION
®
MAX6675 Evaluation Kit
♦ Digitizes and Displays Temperature from a
♦ SPI™-Compatible Serial Interface
♦ Easy-to-Use Menu-Driven Software
♦ Available in an 8-Pin SO Package
♦ Fully Assembled and Tested
♦ Includes Windows 95/98/2000/XP-Compatible
Before beginning, the following equipment is needed:
• DC power supply capable of supplying any voltage
• A user-supplied Windows 95/98/2000/XP-compatible
• A standard 25-pin, straight-through, male-to-female
