Photo diode IC KODENSHI KOD-3005 DIMENSIONS (Unit : mm) 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 MAXIMUM RATINGS Item (Ta=25℃) Symbol Rating Unit VCC Vref PO Topr.
