I am getting pretty deeply into the design process for a velocity coil
seismometer amplifier and filter and have decided to try ot quantify
the relative noise performance of various candidate opamps versus coil
resistance. Here is the list of low noise and general purpose types
(which I have on hand) that I am comparing:
Do you have any suggestions for other candidates I might evaluate?
My biggest difficulty in completing this task has been resolving the
wide variation in noise specifications for the various types to
produce a valid comparison in the DC to 10 Hz frequency range,
especially comparing the chopper types to the others.
