Photo diode IC
KOD-3005
KOD-3005 is a photo IC developed as a detector for
optical pick ups of compact discs. The output
impedance is low and stable due to the I-V amplifier.
The detectors of tracking are set on both sides of 4
segmented photodiodes.
FEATURES
•Bult-in I-V amplifier (current-to-voltage converter)
•Laser beam focusing/positioning is best performed
by 4 segmented photodiodes
•Compact, clear mold package
APPLICATIONS
•Signal ditection, focusing and positioning for CD and
other optical disks
