AMIC Technology
General Description
The ASR8800 is an integrated sensor of ambient light (ALS), Infrared light (IR), Solar_UV_Index (SUVI), and proximity sensing (PS) with an IR VCSEL LD (Laser Diode) embedded. It provides innovative algorithms which can be friendly in application. ASR8800 is a perfect solution for light and PS sensing.
