Analog signal is translated to charges which concurrently are spilled down a plurality of charge coupled device (CCD) channels. The CCD storage electrodes of these channels define potential wells at least some of which are of different size and the number of wells in each channel which receive charge as it attempts to fill the successive wells in that channel with depend upon the analog signal amplitude and the respective sizes of said successive wells. The presence or absence of charge in one or more of the storage wells in each channel is sensed and employed in some cases for indicating the value of a bit of given significance, and in others for inhibiting or permitting the propagation of charge along a CCD channel employed to indicate the value of a bit of lower significance.
