KEMET USEQGCDAC82100, Air Quality Sensor

The KEMET QGC thin film pyroelectric gas sensors have reduced physical size but still provide high sensitivity with fast frequency operation. It employs a highly stable dual sensor in a TO39 package. It also has an internal CMOS operational amplifier with a 10 GO feedback resistor outputting a voltage signal centred around half the supply rail.

Reliable operation over a wide frequency range
Low noise circuit
Analogue output
