Abstract

Pour élargir la gamme de tensions d'un convertisseur analogique-numérique, on branche une tension de polarisation 63 en série avec le condensateur d'accumulation 22, cette tension de polarisation permettant de décaler la tension de sortie du dispositif accumulateur 2 de façon à l'éloigner du niveau de détection pour lequel s'arrête le comptage du compteur 5 du convertisseur. On peut ainsi convertir des tensions pratiquement nulles.To widen the voltage range of an analog-to-digital converter, a bias voltage 63 is connected in series with the accumulation capacitor 22, this bias voltage making it possible to shift the output voltage of the storage device 2 so as to 'move away from the detection level for which the counting of counter 5 of the converter stops. It is thus possible to convert virtually zero voltages.
