C1
2.8V
2.8V
Input pin.
Connect optical reception
diode to GND.
Connect a resistor and
capacitor in series to GND,
and set the frequency
response and gain of "Head
Amp".
When the resistor is large
and the capacitor small, the
gain is small.
When the capacitor is large,
sensitivity decreases in
relation to the transient
response.

C2
1.9V
Connect a detection capacitor
to GND.
When the capacitor is large,
sensitivity decreases in relation
to the mean value detection
and transient response.
When the capacitor is small,
fluctuation of the peak detection
and output pulse width
increases.
The capacitor in usage is
0.01μF (typ.). Set output pulse
width fluctuation and noise
elimination characteristics to be
optimum.
4
GND
GND pin.
Adopt a pattern design that will
allow external parts to be
located as closely as possible
to this pin. Ground them all at
the same point. The transport
distance and noise elimination
characteristics are greatly
influenced by the pattern design
surrounding the GND.

fo
1.4V
Connect a resistor to the
power supply.
Set the center frequency of
the built-in BPF.
See "External resistor at
Pin 5 vs. Center frequency
response" on Page 6.
