Single Supply OP

[Tom]

Hello everybody,

I am looking for a single supply OP where a bandwith of 400Hz is
supported. Does anybody know such a device? I looked at the LM324, it
is not bad but not the specified bandwith.
Greetings Tom

Practically any op-amp other than some very micropower sorts will do 400Hz.
Did you perhaps make a typo?

The bandwidth depends on what gain you are looking for. You can't
judge simply by the location of the dominant pole.

This all depends on what gain you need at 400 Hz. That is why opamps
are specified to have a particular gain*bandwidth product.
