1 / 11 page  APDS-9800 Integrated Ambient Light and Proximity Sensor Data Sheet Description The APDS-9800 integrates ambient light sensor (ALS), proximity sensor (PS) and ambient light cancelation functions in a single module. The module contains three chips in one small package: an ambient light sensor IC, a proximity sensor signal conditioning circuit and a proximity sensor that includes both an LED emitter and detector. The ambient light sensor has a spectral response close to the CIE standard photopic observer and a current output. The proximity sensor signal conditioning circuit has an LED driver and a receiver circuit that has both analog and digital outputs. With the built-in LED, the proximity sensor is able to sense the proximity of an object, such as a finger, hand or head that is close to a portable device. The PS also features an excellent ambient light cancellation circuit for operation in direct sunlight. By detecting the ambient light illuminance level, the ambient light sensor can control the brightness of display backlights. The proximity sensor makes many interesting and useful applications possible. For example, a proximity sensor can detect the proximity of a mobile phone user’s head and turn off or on the phone keypad and LCD backlight. By combining an ambient light sensor and proximity sensor in a single compact module, mobile phones, PDAs and notebooks can have additional features or benefit from increased performance, such as in battery life.
