Overview
TMD2772/ TMD2772WA Digital ALS and Proximity Module General Description The TMD2772/TMD2772WA 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 and are available with 25° and 50° fields of view.
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.
The TMD2772/TMD2772WA ALS is based on the ams patented dual-d...
