Temperature Measurement in a Single Chip

Posted on May 25, 2012

The LTC1392 is designed to be used for PC board temperature and supply voltage/current monitoring or as a remote temperature and voltage sensor for monitoring almost any kind of system. It is available in SO-8 and DIP packages allowing it to fit onto almost any circuit board.

A typical LTC1392 application is shown in Figure 3. A single point star ground is used along with a ground plane to minimize errors in the voltage measurements. The power supply is bypassed directly to the ground plane with a 1mF tantalu
