ABSTRACT:
An MOS, integrated circuit, analog-to-digital converter powered by a single power supply potential and suitable for converting an analog signal equal to that power supply potential is described. The input analog signal is capacitively divided by two; resistor strings interlaced with the resistance ladder of the digital-to-analog converter provides a reduced reference potential. A chopper amplifier is employed in the comparator which includes circuits for reducing offset potentials.
