Photosensor with front-end IC


Compact APD suitable for various light level detection (Φ0.2 mm)


The S15597-01CT is a compact optical device that integrates a Si APD and preamp. It has a built-in DC feedback circuit for reducing the effects of background light. It also provides excellent noise and frequency characteristics. They also provide excellent noise and frequency characteristics. We provide an evaluation kit for these products.
