Digital ST60 Dual Thermopile (Preliminary)

Detector Circuit Overlay

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

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

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

Options

  1. See Standard Windows and Filters (PDF) for list of optical filter options
  2. Available in 3V or 5V configurations

Datasheet
For more information see the datasheet Digital ST60 Dual (PDF).

Specifications apply at 23°C with Nitrogen encapsulating gas.
