TMD2772/

TMD2772WA

Digital ALS and Proximity Module

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-diode technology that enables accurate results and

approximates human eye response 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 for end-equipment calibration due to

component variations.
