ams TMD27723 Ambient Light Sensor. Digital ambient light sensor, proximity sensor and IR LED in an optical module 1.8v I2C TMD27723

The TMD2772 family of devices provides digital ambient light sensing (ALS), a complete proximity detection system, and digital interface 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 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.
