Pour d\u00e9velopper le TCB702FNG, Toshiba a am\u00e9lior\u00e9 sa technologie pour atteindre des niveaux de rendement comparables \u00e0 ceux d’un amplificateur num\u00e9rique classe D \u00e0 haut rendement dans la plage de fonctionnement r\u00e9elle de 0,5 \u00e0 4W. Par cons\u00e9quent, la consommation d’\u00e9nergie du nouvel appareil est r\u00e9duite jusqu’\u00e0 80% par rapport \u00e0 celle d’un amplificateur classe AB typique.<\/p>\n

Le TCB702FNG dispose d\u2019une fonction d’autodiagnostic avec commande par bus I2C, qui permet de diagnostiquer les d\u00e9fauts comme les connexions de sortie crois\u00e9es. Il dispose aussi d\u2019une d\u00e9tection permanente de d\u00e9calage de tension continue en sortie, ce qui permet de d\u00e9tecter rapidement une tension de sortie anormale et ainsi d’\u00e9viter la fatigue des haut-parleurs, pour am\u00e9liorer la fiabilit\u00e9 du syst\u00e8me. D’autres fonctions de protection sont int\u00e9gr\u00e9es notamment contre les surtensions ou les tensions trop basses.<\/p>\n

Le support de l\u2019alimentation en 6V permet au TCB702FNG d\u2019\u00eatre compatible avec les v\u00e9hicules \u00e9quip\u00e9s d’un syst\u00e8me de r\u00e9duction de r\u00e9gime de ralenti, tout en \u00e9liminant les sons \u00ab\u00a0pop\u00a0\u00bb provoqu\u00e9s par les fluctuations de tension d’alimentation.<\/p>\n
