Conçus pour les appareils de santé et les instruments multicanaux portables basse consommation, les amplificateurs ultra-rapides ADA4896-2 (dual), ADA4897-1 (simple) et ADA4897-2 (dual) allient la bande passante la plus large, la vitesse de balayage la plus élevée et le plus bas niveau de bruit actuellement disponibles sur un amplificateur rail-à-rail ne consommant que 10 mW. Chacun de ces trois amplificateurs présente un niveau de bruit de 1 nV\/√Hz et une vitesse de balayage de 120 V\/µs avec une consommation de courant d’alimentation de 3 mA. Par ailleurs, le niveau de bruit en 1\/f à 10 Hz est de seulement 2,4 nV\/√Hz.
\nDans le cadre de cette série d’amplificateurs ultra-rapides, ADI annonce par ailleurs l’amplificateur dual ultra-rapide décompensé ADA4895-2. Ce modèle délivre un produit gain\/bande passante de 1,5 GHz pour des gains supérieurs ou égaux à 10, ce qui en fait un préamplificateur ultra-rapide à gain élevé idéal. Ces nouveaux amplificateurs rail-à-rail fonctionnent dans la plage de température étendue comprise entre -40˚C et +125˚C, sous une tension comprise entre 3 V et 10 V. Les références ADA4895-2 et ADA4897-1\/-2 incluent une fonction de désactivation de la sortie.<\/p>\n
