Photo diode IC
K O D E N S H I
KOD-3005
DIMENSIONS
(Unit : mm)
KOD- 3005 is a photo IC developed as a detector for
o p tic a l p ic k up s o f c o m p a c t d is c s . The o utp ut
impedance is low and stable due to the I- V amplifier.
The detectors of tracking are s et on both s ides 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
