1 APDS-9960 Digital proximity , Ambient Light, RGB and Gesture SensorData SheetDescriptionThe APDS-9960 device features advanced Gesture detec-tion, proximity detection, Digital Ambient Light Sense (ALS) and Color Sense (RGBC). The slim modular package, L x W x H mm, incorporates an IR LED and factory calibrated LED driver for drop-in compatibility with existing detectionGesture detection utilizes four directional photodiodes to sense reflected IR energy (sourced by the integrated LED) to convert physical motion information ( velocity, direc-tion and distance) to a digital information.

2 The architec-ture of the gesture engine features automatic activation (based on proximity engine results), ambient light sub-traction, cross-talk cancelation, dual 8-bit data converters, power saving inter-conversion delay, 32-dataset FIFO, and interrupt driven I2C communication. The gesture engine accommodates a wide range of mobile device gesturing requirements: simple UP-DOWN-RIGHT-LEFT gestures or more complex gestures can be accurately sensed. Power consumption and noise are minimized with adjustable IR LED continued on next Gesture Detection Color Sense Ambient Light Sensing Cell Phone Touch Screen Disable Mechanical Switch Replacement Ordering InformationPart NumberPackagingQuantityAPDS-9960 Tape & Reel2500 per reelFeatures Ambient Light and RGB Color Sensing, proximity Sensing.

4 Color and ALS detectionThe Color and ALS detection feature provides red, green, blue and clear light intensity data. Each of the R, G, B, C channels have a UV and IR blocking filter and a dedicated data converter producing16-bit data simultaneously. This architecture allows applications to accurately measure ambient light and sense color which enables devices to calculate color temperature and control display InterfaceINTSCLSDABlueThreshold ControlGNDG reenRedClearRightLeftDownUpLED KLED AVDDLDR32 x 4 ByteFIFOG esture EngineProximity EngineALSRGBCADCPWMMUXO scillatorProximity detectionThe proximity detection feature provides distance mea-surement ( mobile device screen to user s ear)

5 By pho-todiode detection of reflected IR energy (sourced by the in-tegrated LED). Detect/release events are interrupt driven, and occur whenever proximity result crosses upper and/or lower threshold settings. The proximity engine features offset adjustment registers to compensate for system offset caused by unwanted IR energy reflections appear-ing at the sensor. The IR LED intensity is factory trimmed to eliminate the need for end-equipment calibration due to component variations. proximity results are further im-proved by automatic ambient light Pins ConfigurationPinNameTypeDescription1 SDAI/OI2C serial data I/O terminal - serial data I/O for I2C-bus2 INTOI nterrupt - open drain (active low)3 LDRLED driver input for proximity IR LED, constant current source LED driver4 LEDKLED Cathode, connect to LDR pin when using internal LED driver circuit5 LEDALED Anode, connect to VLEDA on PCB6 GNDP ower supply ground.
