I think we need a lot more information. However it sounds like the amplifier is unstable and going into bursts of oscillations

Hello

Thanks for your reply.

What kind of information do you need?

The basic configuration of the amplifier?

The peripheral hardware is built up according the proposed drawings and confirmed by ST support.
