Digital ST60 Thermopile (Preliminary)

Detector Circuit Overlay

DR34 Compensated Thermopile

A single channel silicon- based thermopile in a TO-5 package that includes integrated electronics which incorporate an industry standard digital SMBus interface. The small active area size is 0.61mm x 0.61mm.

Excellent for gas analysis, environmental monitoring, HVAC and smart home/building control

The digital platform supports easy integration and provides rapid development due to the integrated amplifier, A/D, DSP, MUX and communication protocol
