  • SUCCESSIVE APPROXIMATION REGISTER A/D CONVERTER AND DC/DC CONVERTER
    Publication number: 20120133346
    Abstract: The SAR control circuit of the successive approximation register A/D converter changes the digital value by the first conversion frequency in a first conversion range according to the comparison result signal, and outputs the digital value. When it is determined that the sample and hold value is out of the first conversion range according to the determination signal, the range setting circuit sets a second conversion range different from the first conversion range.
