Abstract
Convertisseur numérique-analogique comportant des sources de courant 1-1 à 1-12 envoyant des courants pondérés à des circuits de commutation associés 2-1 à 2-12, qui aiguillent les courants pondérés soit à une ligne de sortie 14 soit à une ligne de décharge 15. L'ensemble des paires source de courant-circuit de commutation est divisé en deux groupes 4-1 et 4-2, le convertisseur comprenant des circuits 8, 12, 5 et 6, 9, 7 pour assurer la continuité des courants fournis par les sources du premier groupe et les sources du second groupe. Le convertisseur comprend des commandes supplémentaires FORCER et BLOQUER utilisées dans l'application d'un tel circuit à un système de conversion analogique-numérique. Application dans les systèmes de traitement de données.
