Each of the R, G, B, C todiode detection of reflected IR energy (sourced by the in - channels have a UV and IR blocking filter and a dedicated tegrated LED). Detect/release events are interrupt driven, data converter producing16-bit data simultaneously. This and occur whenever proximity result crosses upper and/ architecture allows applications to accurately measure or lower threshold settings. The proximity engine features ambient light and sense color which enables devices to offset adjustment registers to compensate for system calculate color temperature and control display backlight. 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 subtraction.
