A/D conversion circuit and electronic instrument










Image Number 13 for United States Patent #7786918.

An A/D conversion circuit includes an amplifier circuit that includes a plurality of amplifiers that are cascaded, a selector that selects one of output signals output from the plurality of amplifiers and outputs the selected output signal as a selector output signal, an A/D converter that A/D-converts the selector output signal output from the selector, a determination circuit that determines whether or not a voltage of the output signal output from each of the plurality of amplifiers is within a determination voltage range specified by a high-potential-side determination voltage and a low-potential-side determination voltage, and a control circuit that instructs the selector to select one of the output signals output from the plurality of amplifiers based on the determination result of the determination circuit.
