First-stage gain
setting pin
Reverse input pin of the first-stage
amplifier.
Connect a capacitor (0.01
μ
F) to
prevent direct current so that the first-
stage amplifier operates as an AC
amplifier. The gain of the amplifier can
be adjusted by an external resistor (0 to
1 k
) (refer to

Signal input pin
This pin has an internal impedance of
90 k
(TYP.) and can be directly
connected to a PIN photodiode.
Because this is the input pin of a high-
sensitivity amplifier, exercise care that
noise is not superimposed on this pin.
Keep the wiring length of the cathode of
the PIN photodiode as short as possi-
ble.
