ad712jn replacement

[bernat]

Hi, I have a digital crossover and the output opamps are Ad712jn, is possible to replace them with a better ones, any suggestions? thanks in advance

You can try AD823, AD8620, LM4562, OPA 627x2...

Ok, i will try some of them, do you know if is necessary the bypass cap for avoid oscillation problems?
thanks

The AD712 is Jfet and The LM4562 is bipolar, I think I read is problematic to swap jfet with bipolar, I'm correct?

You need to examine the circuit to be sure. It's not neccessarily a problem, but it is something to be aware of. Bipolar types may give considerably higher offset voltages, again depending on the circuit implementation.
