Photosensor amplifier
C2719
G
Avoid using C2719 in locations subjected to excessive
vibrations. If unavoidable, use a low-noise coaxial cable
as the signal input cable.
G
In low-light-level detection circuits, insulation resistance
of the circuit board and other insulation materials can
affect measurement accuracy. Avoid humidity and soiling.
G
Noise increases when the input capacitance becomes
larger, so keep the input coaxial cable as short as pos-
sible.
G
Remove the batteries when C2719 is not to be used for a
long period.
G
An input protection circuit is incorporated, but even so, do
not apply more than ±100 V.
G
For external power supply, use a regulated DC power
supply with a ripple of less than 3 mVp-p. Make sure that
the supply voltage does not exceed ±15 V even momen-
tarily. Avoid using a switching power supply, as this can
cause noise problems during measurement.
I
Precaution for use
G
When an external power supply is used for C2719, volt-
age is supplied regardless of whether the power switch
of C2719 is on or off. Use the power switch of the external
power supply to turn voltage on and off.
G
There are photodiodes whose cathode is connected to
the metal package. To connect the cathode of such a
photodiode to C2719, be sure to hold the photodiode
with insulator as shown in Figure 12. The signal current
cannot be obtained if the photodiode package is
grounded.

Hamamatsu also provides C6386 high-speed photosensor amplifier that incorporates a photodiode at the installation port of
the optical fiber (1 meter long).

l
Easy handling
Built-in photodiode allows easy detection of light just by
connecting to a voltmeter.
l
Optical fiber light input
Measures light at a narrow detection point. Separating the
amplifier from the detection point allows measurement in
unusual environments and improves S/N.
