OPA1612: SoundPlus OPA1612 in replacement of OPA2134

Part Number: OPA1612
Other Parts Discussed in Thread: OPA2134, , OPA1678

Hi Community, TI!!!

I would like to upgrade an audio amplifier OPA2134 and the TI site web recommands me to change for a new OPA.

I found that OPA1612 was in the ultimate soundplus collection that's why i have change for it.

Unfortunatly with the new OPA1612 I have obtained a lot of noise on the output channel.

I try to use a cheap component like NE5532P, no noise, with OPA2134 no noise with the OPA1612 a lot of noise.

Do you know why i obtained this issue with the new OPA1612?

Thanks a lot
