APDS-9190 (BROADCOM LIMITED)

The APDS-9190 is a digital Proximity Sensor provides IR LED and a complete proximity detection system. The proximity function offers plug and play detection to 100mm (without front glass) thus eliminating the need for factory calibration of the end equipment or sub-assembly. The wide dynamic range also allows for operation in short distance detection behind dark glass such as a cell phone. The proximity function is targeted specifically towards near field proximity applications. The digital proximity sensor device is fast enough to provide proximity information at a high repetition rate needed when answering a phone call. This provides both improved "green" power saving capability and the added security to lock the computer when the user is not present. The addition of the micro-optics lenses within the module, provide highly efficient transmission and reception of infrared energy which lowers overall power dissipation.
