S10317 series photo IC integrates a photodiode chip and an IC chip into the same package. The photodiode chip is internally
connected to the IC chip as shown in the block diagram. S10317 series should be used with terminal Ro connected to an external
gain resistance Ro.
A photocurrent is generated when a laser beam enters the photodiode. This photocurrent is fed to the input terminal of the IC and,
after being amplified by the current amplifier, flows to the external gain resistance. At this time, voltages V
given by the following expression.
