Broadcom AFBR-S6PY1943, Environment Sensor for Gas Leak Detectors & Alarms

The Broadcom thin film pyroelectric infrared (IR) sensors for gas detection and other substance concentration measurements, The main use of this high sensitivity device is CO2 detection. It is High-performance current mode sensor that achieves a signal-to-noise of 10,000 and offers a fast, stable response over a wide operating frequency range. The sensor elements are built into a low noise circuit that has an internal CMOS op amp, with a 10 GΩ feedback resistor outputting a voltage signal centered on half the supply rail. This product is lead-free and compliant with RoHS.
