Description
The APS-16D25-11-DF8/TR8 is a digital-output ambient light sensor with built-in IR driver and I²C interface.
The APS-16D25-11-DF8/TR8 has signal processing circuit on a CMOS integrated circuit to provide light
measurements over an effective 16bit dynamic range with a response similar to that of human eye. The
APS-16D25-11-DF8/TR8 uses user-selected modulation frequency to drive the external IR LED and employ
a noise cancellation scheme to highly reject unwanted IR noise. The APS-16D25-11-DF8/TR8 has excellent
temperature compensation, robust refresh rate setting without any external RC low-pass filter. Connected
with an infrared LED (IR-LED), the built-in proximity sensor can reveal the closeness of
approaching/departing objects. This device is intended primarily for use in applications in which
measurement of ambient light and proximity sensing is a necessary, such as laptop computers, PDA,
camcorders, mobile phone, smart phone.
