PY-ITV-SINGLE TO39(2+1) (Rev. 6.1) Thin Film Pyroelectric Single Channel Sensor Introduction Pyreos thin film pyroelectric IR sensors for gas detection and substance concentration measurements offer exceptionally high responsivity, low microphonics and class leading thermal and electrical stability. This high performance current mode sensor achieves a signal to noise of ~10,000 and offers a fast, stable response over a wide operating frequency range. The sensor element is built into a low noise circuit that has an internal CMOS operational amplifier, with a 10 G feedback resistor outputting a voltage signal centred around half the supply rail.
