Digital ALS and Proximity Module Board - TMD2772

The TMD2772 family of devices provides digital ambient light sensing (ALS), a complete proximity detection system, and digital interface logic in a single surface mount module. The devices are register-set and pin-compatible with the TMD2771 family of devices and include new and improved ALS and proximity detection features. The ALS enhancements include a reduced-gain mode that extends the operating range in sunlight. Proximity detection includes improved signal-to-noise performance and more accurate factory calibration. A proximity offset register allows compensation for optical system crosstalk between the IR LED and the sensor. To prevent false proximity data measurement readings, a proximity saturation indicator bit signals that the internal analog circuitry has reached saturation Ambient Light Sensing, Proximity Detection, and IR LED in a Single Module  Register Set- and Pin-Compatible with the TMD2771 Series   Ambient Light Sensing (ALS)  Approximates Human Eye Response  Program
