Bonjour à tous,

Je souhaite amplifier un signal audio avec un montage différentiel à étages. Je ne peux utiliser que des AOP et des résistances simples. Donc pas d'amplificateur d'instrumentation tel que INA , etc.
Auriez vous des recommandations sur les AOP à utiliser et des chémas s'il vous plaît
Merci beaucoup
