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.
