description
the tmd27723 family of devices provides digital ambient light sensing (als), a complete proximity detection system, and digitalinterface logic in a single 8-pin 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 detectionfeatures. 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 factorycalibration. 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 proximitysaturation indicator bit signals that the internal analog circuitry has reached saturation.
the tmd2772 als is based on the taos patented dual-diode technology that enables accurate results and approximates human eyeresponse to light intensity under a variety of lighting conditions. the proximity detection system includes an led driver and an ir led, which are factory trimmed to eliminate the need forend-equipment calibration due to component variations.
