Abstract
A dual analog-to-digital (A/D) converter circuit having two separate channels coupled to receive a single analog input signal, each of the two channels includes a means for converting an analog input signal to a digital signal at respective sample times that are adjustable to be substantially simultaneous; a means for adjusting the gain of the two channels to differ by a predetermined factor; a means for detecting a channel overflow condition in one of the two channels having a higher gain; and a means for merging the two channels into a continuous output stream.
