SENSOR
FEATURES
TYPICAL APPLICATIONS
SMD and Through-hole types
1. Built-in optical filter for spectral
response similar to that of the human
eye.
1. Brightness detection for LCD
backlight control for LCD devices
(LCDTVs, car navigation systems, and
mobile PCs).
2. Brightness detection for circuits in
residential lighting, lighting for
security, and automatic lighting for
bicycle.
2. Photocurrent is proportional to
illumination. (linear output)
3. Uses environmentally friendly
silicon chips.
