Description
APS-12D-1-02/TR8 is a digital-output light sensor, combining two photodiodes and signal
processing circuit on a single CMOS integrated circuit to provide light measurements over an
effective 12-bit dynamic range with a response similar to that of human eye. The integrating
conversion technique employed by the APS-12D-1-02/TR8 effectively eliminates the effect of
flicker from AC-powered lamps, increasing the stability of the measurement. Connected with an
infrared LED (IRED), 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 must, such as laptop computers, PDAs,
camcorders, and GPS systems.
Applications
• Detection of ambient light for controlling the backlighting of TFT LCD display
• Automatic residential and commercial lighting management
• Automatic contrast enhancement for electronic signboard
• Mobile phone, Notebook PC, Net PC, UMPC, GPS… etc.
