Photo IC for laser beam synchronous detection
S10317 series
Low voltage operation (3.3 V)
S10317 series photo IC uses a high-speed PIN photodiode designed for laser beam synchronous detection. S10317 series is driven by a
low voltage (3.3 V) compatible with low voltage peripheral components that will be mounted on the same PC board. Two types of current
amplifiers are available with a gain of 6 times (S10317-01) and 20 times (S10317) that can be selected according to laser power to be
used. Tape-and-reel shipment is also available (S10317-30 and S10317-31).
