C9329_15 Datasheet, PDF (2/4 Pages) Hamamatsu Corporation – Digital output function, current-to-voltage conversion amplifier for amplifying very slight photocurrent with low noise

Photosensor amplifier C9329
s Typical connection to photodiode
This is an example using a photodiode whose cathode is
internally connected to its metal package.
When you use a photodiode metal package, use an insu-
lator to electrically insulate and also hold the package in
a shield case as shown in the figure at right. Connect the
anode to the shield case.
Any single-element photodiode with a terminal capaci-
tance below 5000 pF can be used.
Using a photodiode with anode grounded is recom-
mended.
Using a photodiode with a BNC connector (S2281 se-
ries) allows you to easily make measurements because it
connects to C9329 with a BNC-BNC plug coaxial cable.

Photodiode, coaxial cable with BNC-BNC plug and RS-232C cable are not supplied with C9329. You will need an RS-232C
cable (straight cable terminated with a D-sub 9 pin female connector at both ends) available from electronics supply houses.
