Le LM48903 rejoint une famille de CI audio innovants à effet spatial, conçus spécialement pour les applications où l’encombrement est limité, des smartphones aux télévisions à écran ultraplat.
\nLe circuit comprend un DSP de traitement spatial, deux amplificateurs de classe D, un convertisseur analogique-numérique (ADC) stéréo 18-bits, une boucle à phase asservie (PLL) et des interfaces I2S et I2C.  Un logiciel facile à utiliser accélère les développements si bien que l’utilisateur n’a plus besoin d’avoir recours à l’ajustement d’algorithmes et à des experts DSP en interne. Deux transducteurs de haut-parleurs de classe D fournissent un courant de sortie continu de 2 W avec une charge de 4 Ohm et une distorsion harmonique totale bruit compris de moins de 1% (THD + N), afin de simplifier la conception système et réduire les coûts de matériaux. L’effet audio immersif permet d’ignorer les limitations physiques du système pour offrir une expérience sonore étendue.
\nL’outil en ligne de conception de matrices pour haut-parleur avec LM48903 comprend un générateur de coefficient facile à prendre en main pour créer des coefficients audio spatiaux uniques en quelques manipulations simples. Des pilotes Android et un tableau d’évaluation doté d’une interface utilisateur graphique sont aussi inclus.<\/p>\n
