PHOTO IC
Photo IC for laser beam synchronous detection
S9703-10/-11
High sensitivity, high-speed response
S9703 series photo IC uses a high-speed PIN photodiode designed for laser beam synchronous detection. When compared to S9703 and
S9703-01 previously marketed, S9703-10 and S9703-11 have reduced their reflection effects in the package. Two types of current
amplifiers are available with a gain of 6 times (S9703-11) and 20 times (S9703-10) that can be selected according to laser power to be
used. Tape-and-reel shipment is available (S9703-30 and S9703-31). HAMAMATSU also provides S9684 series photo ICs that use a dual-
element Si PIN photodiode.
