Abstract
An analog-to-digital conversion circuit of the type employing a feedback-type, successive subranging mode of operation is provided. The circuit achieves bipolar input capability using an internal subranging A/C converter which has only a unipolar capability using a single level, unipolar, add-only binary summer to combine successive subranges. The foregoing have been achieved by means of a novel combination of relatively simple circuit elements which have fast settling times.
