AFBR-S6PY3151 - Thin film analog pyroelectric dual-channel high sensitivity sensor with a 3.91 µm / 90 nm filter and a 3.30 µm / 160 nm filter for CH4 detection

Product Detail

Broadcom's thin film pyroelectric infrared (IR) sensors for gas detection and other substance concentration measurements offer exceptionally high responsivity, low microphonics and class-leading thermal and electrical stability. The analog dual detector AFBR-S6PY3151 has a reference channel with a 3.70 µm / 110 nm filter and one channel with a 4.26 µm / 180 nm filter. The main use of this high sensitivity device is CO2 detection. 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 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.
