Affordable IR detection module based on InAsSb temperature stabilized photovoltaic detectorAMS3140-01
Temperature stabilized, integrated amplifier and temperature controller
The AMS3140-01 is a cost-effective solution designed for high volume applications. Built-in amplifier and temperature controller provide constant responsivity over a wide range of ambient temperatures. Wide bandwidth and low 1/f noise corner provide efficient measurements with generally available sources of radiation, including MEMS heaters, and pulsed LEDs or lasers. With differential output, the AMS3140-01 offers easy connectivity over connectors with high immunity to electromagnetic interference. Small dimensions provide easy mechanical and thermal integration with the target device.
For testing performance and evaluating the functionalities of the AMS3140-01, the Evaluation Kit and additional accessories are available.
