L’ADC se r\u00e9initialise compl\u00e8tement apr\u00e8s chaque \u00e9chantillon, effa\u00e7ant toutes les erreurs r\u00e9sultant d’un seul \u00e9v\u00e9nement perturb\u00e9 (SEU) d\u00fb \u00e0 un rayonnement ionique intense pendant le vol spatial.<\/p>\n

L’ISL73141SEH est l’un des principaux \u00e9l\u00e9ments constitutifs du parcours du signal dans les satellites de communication en orbite terrestre g\u00e9osynchrone \/ g\u00e9ostationnaire de longue dur\u00e9e (GEO) et les engins spatiaux habit\u00e9s, y compris les missions spatiales lunaires. En offrant les meilleures performances dynamiques et statiques du secteur, le nouvel ADC 14 bits capture avec pr\u00e9cision les transmissions analogiques du monde r\u00e9el et les convertit pour un traitement dans le domaine num\u00e9rique. L’ADC ISL73141SEH est l’un des sept circuits int\u00e9gr\u00e9s, y compris un capteur de temp\u00e9rature rad-hard, un multiplexeur, un amplificateur op\u00e9rationnel quad, un driver ADC, un r\u00e9gulateur LDO et une r\u00e9f\u00e9rence de tension pour former une solution compl\u00e8te de cha\u00eene de signaux d’interface de capteur qui acc\u00e9l\u00e8re la t\u00e9l\u00e9m\u00e9trie, le suivi et le contr\u00f4le (TT&C) et d\u00e9veloppement de syst\u00e8mes informatiques de vol.<\/p>\n

\u00ab L’ISL73141SEH offre aux fabricants de satellites et d’engins spatiaux le summum des performances ADC combin\u00e9es \u00e0 une cha\u00eene de signaux d’interface de capteur de premier ordre \u00bb, a d\u00e9clar\u00e9 Philip Chesley, vice-pr\u00e9sident de la division commerciale industrielle et communication de Renesas. \u00ab Notre ADC 14 bits de qualit\u00e9 spatiale offre des performances de conversion de donn\u00e9es nettement meilleures que toute autre solution concurrente, et il est soutenu par six d\u00e9cennies de leadership dans les tests et la caract\u00e9risation des performances de rayonnement qui donne aux clients des vols spatiaux l’assurance de mission qu’ils exigent. \u00bb<\/p>\n
