AP3220
The AP3220 is an integrated module that includes a digital ambient light sensor [ALS], a proximity sensor [PS] in a Chipled RoHS package. This device provides a multiple gain function with linear response over a dynamic range 1023/4095/16383/65535 and is well suited to applications under clear glass or darkened glass.

The proximity function is targeted specifically towards near field application and detects external object with simple configurable zone controlled by registers. With multiple proximity gain control and 10-bit ADC output, this device is designed specially to fix low reflection objects, such as black hair.

The device supports an interrupt feature to improve system efficiency and several features that help to minimize the occurrence of false triggering. Through internal calibration and CMOS design, the AP3220 is designed to minimize device-to-device variations for ease of manufacturability.
