Abstract: An analog to digital converter comprising at least one sampling capacitor connected to a sample node, and a pre-charge circuit arranged to cause the voltage on the sample node to substantially match the input voltage prior to the analog to digital converter entering an acquire mode in which the sample node is connected to the input node by a sample switch.
