Affordable IR detection module with an integrated differential amplifierAM03100-02
The AM03100-02 is a cost-effective infrared detection module designed for high-volume applications. The detection structure is optimized for wavelengths up to 5 µm. The built-in differential amplifier provides high immunity to electromagnetic interference. Wide frequency bandwidth and low 1/f noise corner frequency provide efficient measurements with generally available sources of radiation, including MEMS heaters and pulsed LEDs or lasers. Small dimensions and solderable PCB provide easy mechanical integration with the target device.
