The AP3216C is an integrated ALS & PS module that includes a digital ambient light sensor [ALS], a proximity sensor [PS], and an IR LED in a single package.
This device provides a multiple gain function with linear response over a dynamic range 365/1460/5840/23360 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, multiple IR LED current 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.
