Abstract

L'invention concerne les convertisseurs analogiques-numériques programmables. Elle se rapporte à un convertisseur dans lequel un réseau en échelle, destiné à transmettre des tensions de référence à des comparateurs, est piloté en plusieurs noeuds de commande par des jeux de tensions programmés provenant par exemple d'un réseau résistif ou d'une source de signaux numériques. La fonction de transfert peut être modifiée en fonction du temps. Application aux appareils ultrasonores de diagnostic médical.
