Avec un bruit très basse fréquence de seulement 0,5 ppm, une dérive en température (CT) maximale de 2 ppm\/°C sur l’ensemble de la plage de température comprise entre -40 et +125°C ainsi qu’une dérive à long terme de 25 ppm\/1000 heures, ces circuits garantissent un haut niveau de précision dans le temps et indépendamment des variations de température, ce qui constitue un atout déterminant pour de nombreuses applications de haute précision. Ces excellentes performances sont obtenues à un courant de repos maximum de 950 µA, ce qui destine tout particulièrement ces produits aux applications portables où le coût constitue également un paramètre sensible. D’ailleurs, une version économique est également proposée avec un coefficient de température de 5 ppm\/°C.
\nTous ces composants sont disponibles en boîtier SOIC-8 avec des tensions typiques de sortie de 2.048 V (ADR4520), 2.5 V (ADR4525), 3.0 V (ADR4530), 3.3 V (ADR4533), 4.096 V (ADR4540) et 5.0 V (ADR4550) pour une tension d’entrée de 3 à 15 V. Ils peuvent être associées à différents convertisseurs propriétaires analogique\/numérique haute précision et basse consommation tels que les modèles AD7685, AD7982 et AD7988-1\/-5, ainsi qu’à des convertisseurs numérique\/analogique tels que les modèles AD5780 et AD5764.<\/p>\n
