Phot diode IC
KODENSHI
KOD-2410
DIMENSIONS
KOD-2410
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.
(Unit : mm)
FEATURES
鈥ult-in I-V amplifier (current-to-voltage converter)
鈥aser beam focusing/positioning is best performed
by 4 segmented photodiodes
鈥ompact, clear mold package
APPLICATIONS
鈥ignal ditection, focusing and positioning for CD and
other optical disks.
