TMD2771 Description
The TMD2771 family of devices provides digital ambient light sensing (ALS), a plete proximity detection system, and digital interface logic in a single 8-pin package. The proximity detector includes a digital proximity sensor, LED driver, and IR LED, which are trimmed to eliminate the need for end-equipment calibration due to ponent variations. Excellent background light rejection allows the device to operate in...
