I'm making bubba oscillator (phase shift oscillator with 4 RC filters).
For this I need to use 4 op-amps
Can someone please tell me which quad amp chip will be the best to use and Why?

I have consider some such as TL084, LM348 or using 4 LM741
but can't decide on which is the best one to use?

any help will be great

For low frequensiz, I beleive it doesn't matter that much what opamp you use.

What frequens area are you going to use?

hey thanks for the reply

I'm looking for 10V rms with frequency of 50Hz I'm thinking about using Bubba oscillator.

At 50hz it won't matter what op-amp you use.

But don't use 4 741s if you can use one LM324 or similar... TL084 is the best in your list, or even better, TL074. If you have a quad op-amp IC in your box o'stuff, use it...
