Cet amplificateur offre une vitesse de balayage améliorée de 19 V\/µs qui permet à la tension de sortie d’atteindre 140 V en moins de 8 µs. Le produit gain x bande-passante est de 10 MHz. Il est optimisé à la fois pour des mises en œuvre à impédance élevée et celles sensibles aux courants de fuite. En plus du boîtier standard SO-8 à semelle radiateur, ce composant est disponible en un boîtier TSSOP à broches de protection de couplage. Ceci permet l’implantation d’une boucle de protection autour de l’entrée.
\nLes caractéristiques thermiques sont un souci pour tout système à espace contraint, de forte tension. Ce dispositif a été conçu pour satisfaire ces exigences. Le courant d’alimentation est de seulement 3,9 mA maximum et l’intensité du courant de sortie est de ±10 mA typique. Une broche "indicateur thermique" (TFLAG) signale quand la température de jonction du composant dépasse 145 °C. Cette broche peut être connectée à une broche "désactivation de la sortie" pour une gestion thermique active. Les deux versions, en boîtiers TSSOP-16 et SOIC-8, possèdent une semelle radiateur pour minimiser la résistance thermique. Elles sont disponibles dans les trois classes de température de jonction de 0 °C à 70 °C, -40 °C à +85 °C et -40 °C à +125 °C. <\/p>\n<\/p>\n
