ABSTRACT:
A first amplifier circuit samples and amplifies an input analog signal by a gain of 0.8 and outputs the amplified signal to a first subtracter circuit. A first analog-digital converter circuit converts the input analog signal into a digital value so as to retrieve the higher 4 bits. A first digital-analog converter circuit converts the digital value produced by conversion by the first analog-digital converter circuit into an analog value. The first subtracter circuit subtracts an output analog signal from the first digital-analog converter circuit from an output analog signal from the first amplifier circuit. The output analog signal from the first digital-analog converter circuit is amplified by a gain of 0.8. By setting the gain of the first amplifier circuit to be below 1, an input voltage range is extended.
