The left end pin is designated No. 1 when viewed from the component side with the pins facing downwards.
q Using pin No. 2
Use pin No. 2 when changing the feedback constant which is typically 50 MΩ/2 pF. Connect feedback resistance and capaci-
tance between pin No. 2 and No. 9. Note that this connection is made parallel to the internal feedback resistance and capaci-
tance.

q Changing the feedback resistance and capacitance
If you want to change the feedback constant without making
parallel connections, directly replace the resistor (Rf) and ca-
pacitor (Cf) shown at the right, which serve as feedback resis-
Cf
tance and capacitance.
Rf
Replacement components shoud be 2012 size.
q Using through-holes A and B
When H4083 is not covered with protective coating, a photo-
diode (such as S3590 series) can be directly soldered on the
board. In this case, insert the photodiode leads into the through-
holes from the solder side.
