Abstract
The invention concerns an analog to digital converter (ADC1, ADC2) for converting an analog input voltage (Vin) into a digital output voltage (Dout) in at least two stages, (B1, B2, B3, B1', B2', B3'). The reference voltage (Vref) or part thereof driving a stage is applied to that stage via switching means so that the voltage applied to the latter means is determined when the switching means is set, i.e. the latter voltage is not dependent of the setting of the switching means. Two implementations of the converter are described, one (ADC1) which produces the digital signal (Dout) before another analog voltage (Vin) can be processed, and another (ADC2) which allows another analog voltage (Vin) to be processed by a stage after the output of that stage is produced.
