Outre l’int\u00e9gration d’un circuit d’amplificateur d’erreur de r\u00e9ponse rapide nouvellement mis au point et d’une architecture \u00e0 faible niveau de bruit, de nombreux param\u00e8tres s’av\u00e9rant impacter la qualit\u00e9 audio dans le d\u00e9veloppement et les processus de fabrication ont pu \u00eatre optimis\u00e9s par le biais de tests pratiques d’\u00e9coute, pour obtenir la meilleure performance du secteur au niveau de toutes les caract\u00e9ristiques cl\u00e9s (stabilit\u00e9 de la tension, niveau de bruit et sym\u00e9trie de l’alimentation \u00e9lectrique) exig\u00e9es pour l’alimentation \u00e9lectrique de l’\u00e9quipement audio.
\nR\u00e9cemment, la popularisation des sources audio \u00e0 haute r\u00e9solution a fait augmenter la demande en composants et appareils audio offrant une reproduction sonore encore plus pr\u00e9cise. Parall\u00e8lement, l’alimentation \u00e9lectrique a un impact consid\u00e9rable sur la qualit\u00e9 du son. Les CI d’alimentation \u00e9lectrique jouent donc un r\u00f4le important dans l’apport d’un courant propre avec une fluctuation et un bruit r\u00e9duit au minimum. Un courant propre implique l’optimisation des trois caract\u00e9ristiques cl\u00e9s : stabilit\u00e9 de la tension, niveau de bruit et sym\u00e9trie entre les arriv\u00e9es de courant positif et n\u00e9gatif. Cependant, jusqu’alors, aucun CI n’\u00e9tait en mesure de r\u00e9pondre \u00e0 ces besoins, et il \u00e9tait impossible d’am\u00e9liorer encore plus la qualit\u00e9 du son. C’est d\u00e9sormais chose faite, puisque ROHM a mis au point les premiers CI d’alimentation \u00e9lectrique audio o\u00f9 les 3 caract\u00e9ristiques sont excellentes, alliant une technologie de conception analogique d’alimentation \u00e9lectrique brevet\u00e9e, \u00e0 une expertise en mati\u00e8re de qualit\u00e9 audio. On obtient ainsi une alimentation \u00e9lectrique tr\u00e8s propre, avec des solutions conventionnelles, permettant d’obtenir une meilleure qualit\u00e9 audio, o\u00f9 m\u00eame l’image sonore (localisation et distance de la source sonore) et la r\u00e9solution (r\u00e9alisme et profondeur) ont \u00e9t\u00e9 am\u00e9lior\u00e9es.
