This technical note describes the first programmable and

pre-calibrated, fully integrated thermopile module (TPMI)

with ambient temperature compensation in TO-5 housing.

The new product is designed with a powerful integrated

circuit (ASIC), combining the thermopile sensor with

signal processing and interface for calibration and

configuration on a small space.

Digital calibration via a serial interface enables a plug &

play function. Memory cells and register access offer a

maximum of flexibility to change factory calibration or

settings for adaptation of the sensor to the specific

application.

With its superior performance over today’s thermopile

modules with discrete external circuit, the PerkinElmer

TPMI has the potential to advance fast into existing and

new applications.

For development purposes, an application kit is available,

which enables the access of all features via a PC based

program.
