Photo IC for laser beam synchronous detection
S10317 series S11257 series
Low voltage operation (3.3 V)
The S10317/S11257 series photo IC use a high-speed PIN photodiode designed for laser beam synchronous detec-
tion. They operate at a low voltage (3.3 V) compatible with low-voltage peripheral components mounted on the same
PC board. Two types of current amplifiers are available with a gain of 6 times (S10317-01, S11257-01DT) and 20 times
(S10317, S11257-02DT) that can be selected according to laser power to be used. HAMAMATSU also provides a 5 V op-
eration type (S9703 series) and dual-element Si PIN photodiode types (S9684 series, S11282-01DS).
