Online Simulation of the Infrared Thermopile Detector ...

2015-02-06· This amplifier is designed for a thermopile infrared detector such as an S60M from Dexter Research. This detector output is 101mV/mW with a source resistance of 90k. A CMOS autozero OPA335 is used to minimize offset and drift as well as 1/f noise. The detector response time is 12ms so the amplifier frequency response is rolled off to minimize its total output noise.

Thermopile Sensor : 6 Steps - Instructables

Check out the circuit diagram for how the op-amp boosts the voltage of the thermopile. The two resistors R1 and R2 provide feedback to the op-amp. The amount voltage boost is set by the ratio between them. In our case R1 is 1MOhm (1000KOhm) and R2 is 1KOhm. 1000K/1K is 1000, so the voltage is boosted 1000 times.
