C9329
Digital output function, current-to-voltage conversion amplifier for amplifying very slight photocurrent with low noise
C9329 is a current-to-voltage conversion amplifier used to amplify very slight photocurrent from a photodiode with very low noise. Three ranges
of photocurrent detection sensitivity level (H, M, L) are selectable to match the input signal. C9329 operates on the built-in dry batteries so it can
be easily used anywhere. C9329 can be directly connected to a personal computer through the RS-232C interface allowing you to acquire highresolution (16-bit) digital output signals and use the data logger function.

■ 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 insulator 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 capacitance below 5000 pF can be used.
Using a photodiode with anode grounded is recommended.
Using a photodiode with a BNC connector (S2281 series) 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.

Si photodiode with BNC connector
S2281 series photodiodes are sealed in a metal package with a BNC connector and designed to connect to C9329 photosensor amplifier. Two
different spectral response ranges are provided. The large active area makes S2281 series suitable for optical power meters. A variant type
S9219 with a visual compensation filter is also available.Hamamatsu also provides E2573 BNC-BNC coaxial cable (length: 1 m) as an option.
