IS1640
OPIC Light Detector
OPIC Light Detector for DVD-ROM/DVD Player (2X Speed)
General Description Outline Dimensions
SHARP's IS1640 is OPIC light detector for pick-up of
DVD-ROM/DVD player which is expected as next
generation media.
It is also applicable to 2X speed DVD-ROM/DVD player.
It has sensitivity switching terminal which enables to read
both 1-layer disc and 2-layer disc.
Features
(1) OPIC light detector for RF signal detection
(Integrates 6-division PIN photodiode and Amp. IC
onto a single chip)
(2) High speed response
(Response frequency : MIN.20MHz)
(3) High sensitivity
(Sensitivity : TYP.40.5mV/µW at 650nm)
(4) With sensitivity switching terminal which enables to
read both 1-layer/2-layer disc
(5) Compact and thin package
(Package dimensions : 5.0 x 4.0 x 1.5mm)
(6) Possible to supply custom-made detecting patterns
(7) Pair use with SHARP's laser diode is recommended.
Laser diode : 650nm (self pulsation) LT055 series
650nm LT056 series
Application
* "OPIC" (Optical IC) is a trademark of the SHARP Corporation.
