Abstract

L'invention a pour objet un dispositif convertisseur analogique-numérique de grande précision. Le dispositif comprend un convertisseur analogique-numérique 2 de précision relativement faible qui fournit périodiquement un mot numérique représentant un échantillon d'une grandeur analogique, et des moyens numériques additionneurs 3 permettant de sommer cumulativement une suite de mots numériques de manière à fournir une information numérique présentant un plus grand nombre de bits qu'un mot. Un générateur de fonction il permet de traiter l'information de façon plus complexe. Le dispositif est particulièrement utile lorsqu'il s'agit d'une mesure qui est une fonction du temps d'intégration d'une valeur analogique.The subject of the invention is a high precision analog-to-digital converter device. The device comprises an analog-to-digital converter 2 of relatively low precision which periodically supplies a digital word representing a sample of an analog quantity, and digital adding means 3 making it possible to cumulatively sum a sequence of digital words so as to provide digital information. having a greater number of bits than a word. A function generator it allows information to be processed in a more complex way. The device is particularly useful when it comes to a measurement which is a function of the integration time of an analog value.
