ams OSRAM TMD27723 Digital Ambient Light Sensor

ams OSRAM TMD27723 Digital Ambient Light Sensor supports a programmable IR LED in an optical 1.8V module with I²C. TMD27723 features ambient light sensing (ALS) enhancements such as 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.
