Abstract

A successive approximation analog to digital converter comprising a plurality of capacitors which during a successive approximation conversion are selectively connectable to a first reference or a second reference under the command of a controller. During a conversion step where the connections of a given capacitor may be varied, the switches to the given capacitor are both placed in a high impedance state during a decision period of a comparator.
