FAIRCHILD KDT00030

KDT00030
Phototransistor Photo Detector
Features
Description
■ Spectral response close to human eye
The KDT00030 is a small, low profile photo detector. It
incorporates a phototransistor detector chip which makes
it an ideal choice for low cost ambient light measurement
applications like mobile appliances backlighting.
■ Good output linearity across wide illumination range
■ Small footprint: 1.7mm x 0.8mm
■ Low profile: 0.6mm
■ Phototransistor with filter technology
Applications
■ Cell Phones, Notebook PCs, PDAs, Digital Still
Cameras
