Optical Proximity Sensor Combines Signal Conditioning, Emitter and Detector
Avago Technologies announced a thin, integrated optical proximity sensor for use in a wide range of portable consumer electronic devices, and personal computers. The APDS-9120 proximity sensor combines a built-in signal conditioning IC, emitter and detector into a single package which offers both analog and digital output options. With a surface mountable package size that is 1.1 mm x 4.4 mm x 4.4 mm, the APDS-9120 offers an extended detection range, and desirable signal conditioning circuitry for performance in bright sunlight conditions. Additionally, this integrated proximity sensor eliminates the need for an external LED driver, signal filtering and amplification, as well as sunlight and ambient light immunity. This sensor also incorporates a stuck high protection circuit to preserve LED life.
