Preliminary YB8000
High-Performance Ambient Light Sensor
Description
The YB8000 is an ultra-compact surface
mount ambient light sensor IC for detecting
ambient light illuminating intensity. The
sensitivity is superior to that of a
phototransistor, and exhibits little
chip-to-chip variation. It has excellent
spectral sensitivity to the illuminating light
source and excellent output linearity. It is
suitable in the power-saving control for
back light display in mobile phones,
notebook computers, PDAs, digital
cameras and video cameras.
