The Broadcom thin film pyroelectric infrared flame detectors/IR sensors an analog single is current mode sensor that has excellent signal to noise at the signature 8-10 Hz flicker range of a flame and can provide accurate discrimination of flame sources in triple IR flame detection systems. The sensor element is built into a low noise circuit that has an internal CMOS op amp with a 10GΩ feedback resistor outputting a voltage signal centered on half the supply rail.
High responsivity and SNR Thermally stable to slow drift and thermal shock Wide filter choice Extended temperature range Less external gain required Reliable and easy to use
