Avago Technologies Announces APDS-9800, Ultra-Thin Integrated Sensor Module for Use in Mobile Phones

APDS-9800 is a module that integrates functions of ambient light sensor (ALS) and proximity sensor (PS). The sensor is composed of three chips in one small package: ambient light sensor IC, proximity sensor signal conditioning circuitry and a proximity sensor that includes both emitter (LED) and detector. The ambient light sensor has current output, with spectral response close to the CIE standard photopic observer. The proximity sensor signal conditioning circuitry consists of LED driver and receiver circuit with both analog and digital output, featured with excellent ambient light cancellation capability. With built-in LED, the proximity sensor is able to sense the proximity of an object, such as finger or head to a portable device. Ambient light sensor can be used to control the brightness of display backlighting by detecting the ambient light illuminance level. Proximity sensor will make more applications possible. For example, it can detect the proximity/departing user’s head and turn off/on the keypad and LCD backlight. The combination of ambient light sensor and proximity sensor in one module makes it ideal for applications in portable devices, such as mobile phone, PDA and notebook…
