Visible Radiant Optical Sensor /Data Sheet
TDK Visible Radiant Optical Sensor is the photo-IC which uses an amorphous
silicone semiconductor technology.
It
is the most suitable for Brightness
Adjustment, Control of the Lighting systems. BCS2015A1 has current-
amplifire in it. BCS2015A1 is for surface mounthing.
Features
• Highly receptive to visible light but not receptive to infrared light (close to
Human eye visibility).
• Accurate illumination measurement can be taken without the use of an
infrared filter.
( Phototransistors and photodiodes that use crystal- silicon semiconductors
typically require this filtering.)
• High output (Built-in current amplifire)
• Surface mounting can be used in lead- free reflow soldering.
• Lead- free, Cadmium-free
BCS2015A1
Application
• Brightness control for LCD, EL and CRT
• Brightness control for Keypads (e. g. Mobile Phones)
• Positioning scanline for Rear Projecton TV
• Exposure adjust for Compact Camera
• Sub exposure adjust for Digital Camera
