FEATURES
1. Built-in optical filter for spectral
response similar to that of the human
eye.
2. Photocurrent is proportional to
illumination. (linear output)
3. Uses environmentally friendly
silicon chips.
TYPICAL APPLICATIONS
1. Brightness detection for LCD
backlight control for LCD devices
(LCD TVs, car navigation systems, and
mobile PCs).
2. Brightness detection for circuits in
residential lighting, lighting for
security, and automatic lighting for
bicycle.
3. Household applicances (day/night
energy savings for air conditioners
and electric hot water pots, etc.)
4. Brightness detection for wall clocks
(radio clocks).
1. Brightness detection for LCD
backlight control for compact mobile
devices (mobile phones and PDAs).
2. Brightness detection for controlling
the keypad backlight in mobile
phones.
