Default substitute OPA Texas TL071CP ?

I arrange of an amplificador integrated CEC AMP 3 double balanced, which mounts some OPA' s of entrance of Texas TL071CP (JFET 200 V/mV, Sleew Rate 13 V/micro seg. ..). It wanted that someone oriented me upon which serious the best OPA than podria to substitute to the Texas, that parametros he should verify so that the compatibilidad he be total. All it because the sound of this amplificador is little dinamicoy noisy.
Cordial greetings.

Try a Burr-Brown OPA604. It is a pin-for-pin substitute for the TL071 and a much better and quieter op-amp.

You might try getting free samples from Burr-Brown or you can readily buy them from Digi-Key (

OPA132 is another good choice.
