摘要： Method and device for converting analogue signals, of a plurality of pathways, into digital signals. A common circuit (2, 3) generates first analogue signals corresponding to high-order bits of digital signals For each pathway, a first means compares the first analogue signals with the signal to be converted. A first means (18) stores high-order bits corresponding to the value of a first analogue signal close to the signal to be converted. A means (9) stores the deviation between the analogue signal to be converted and said first detected value. A generator means (11, 12) generates a predetermined number of second analogue signals. A second means compares by successive approximations said second analogue signals with said deviation. A means (20) stores said low-order bits corresponding to the results arising from said second means of comparison. A means (22) assembles said high-order bits and said low-order bits.
