Photo diode IC KOD-3005 DIMENSIONS 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. (Unit : mm) FEATURES UBult-in I-V amplifier (current-to-voltage converter) ULaser beam focusing/positioning is best performed by 4 segmented photodiodes UCompact, clear mold package APPLICATIONS USignal ditection, focusing and positioning for CD and other optical disks MAXIMUM RATINGS Item Supply voltage Reference voltage Power dissipation Operating temp.
