ABSTRACT:
A dual slope analog to digital (A/D) converter starts by auto zeroing and making a number of high speed A/D samples before auto zeroing again. A microprocessor causes output of the high speed samples for a bar graph and applies predetermined correction factors to allow accumulation of the high speed samples to provide a high accuracy numerical output.
