hcm series

hcm series-大富豪官方网站

the hcm series provides a thermopile sensor chip and optical filter suited to the application plus an analog asic for signal conditioning inside a small smd package. the gain of the asic can be preset to either 2150 or 4300 by an internal pull-up resistor. with the integrated linear temperature reference changing ambient temperature can be compensated for. the sensor supply voltage can be chosen in the range between 2.7 v and 5 v.

  • small leadless smd package
  • integrated asic with analog output
  • integrated linear temperature reference
  • large number of optical filter options
  • large operating range -20°c to 120°c
  • ideal for gas concentration measurements
