Ce convertisseur courant-numérique 24 bits à 256 voies est monté dans un boîtier BGA de seulement 15 mm² à 324 billes au pas de 0,8 mm. Il occupe environ 33 % moins d’espace sur le circuit imprimé que d’autres solutions dont la densité de voies est deux fois inférieure. Ce pas de 0,8 mm permet aux concepteurs de monter ce composant sur un substrat de circuit imprimé standard, ce qui représente une option moins onéreuse et au rendement supérieur que les substrats haute densité spécialisés qui requièrent le perçage de trous au laser.
\nOutre l’intégration de 256 amplificateurs intégrateurs faible consommation, faible bruit et faible courant de polarisation, d’échantillonneur-bloqueurs simultanés et de deux convertisseurs A\/N rapides avec fréquences d’échantillonnage configurables, ce module incorpore tous les amplificateurs internes associés, ainsi que la totalité des capacités de découplage, ce qui réduit le nombre de composants et simplifie la conception de la carte. De plus, il ne consomme que 3 mW par voie indépendamment du débit, une valeur identique à la majorité des circuits de conversion qui comptent seulement 128 voies. <\/p>\n<\/p>\n
