综述

The LS-9800 is a Digital light sensor (DLS) which integrated ALS, proximity detection and IR_LED in an optical module.The LS-9800 consists of an array of photodiode and two wide-dynamic range channels for ambient light and infrared light sensing (LS).The LS-9800 also include additional photodiodes and theirs readout channel, and a factory calibrated IR LED Driver for proximity detection sensing (PS). Both the ALS and PS function independently and with a 16 bit convert result .
