AFBR-S6PY1943 - Thin film analog pyroelectric dual-channel sensor with a 3.91 µm / 90 nm filter and a 4.30 µm / 110 nm filter for CO2 (narrow) 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-S6PY1943 has a reference channel with a 3.91 µm / 90 nm filter and one channel with a 4.30 µm / 110 nm filter. The main use of this device is CO2 (Narrow) 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.
