Digital-to-analogue converter (DAC) comprising means for splitting a digital number to be converted into a more significant part and a less significant part, two DAC means, a resistive chain connected between the outputs of the said DAC means and having 2<N>nodes (where the less significant part has N digits), switches between each node and common output terminal, means for supplying the DAC means with the digit of the more significant part (of value A) and the digital value (A+1) respectively, and means for closing the switch at that node numbered from the DAC means to which the value A is fed corresponding to the value of the less significant part. The invention further provides an anologue-to-digital converter (ADC) employing similar DAC means. |
