LM76 12-bit + Sign Temperature Sensor Evaluation Kit Manual
1.0 General Description
The LM76 Evaluation Kit allows quick connection and evaluation of the LM76CNM 12-bit plus Sign
Temperature Sensor integrated circuit. The LM76CNM is targeted for an accuracy of +/-1 °C in the
temperature range of 70 to 100 °C. The Evaluation Board connects to and derives all of it’s power from
the parallel printer port of a PC. The software was written using Visual Basic 4.0 is compatible with
Windows version 3.1 or later.
With the LM76 Evaluation board and software you can:

Save LM76 temperature measurements in a file
Quickly gain knowledge of the LM76 register operation
Insert the floppy into the 3.5” floppy drive of the PC. Install the software in Windows by selecting
Run and type in the name of the drive followed by “setup”. For example type a:\setup.
In setup select the drive you would like the software installed on. Disk space required for the
software is 1MB.
Make sure all the jumpers are installed on the Evaluation board as shown in figure 1.
