The application provides a single-ended SAR ADC circuit with lockable capacitor array and a working method thereof, which comprises a sample and hold circuit, a comparator, a SAR control logic module and a DAC capacitor array with a lock switch. Before starting the analog-digital conversion, it is necessary to determine whether the lock switch in the capacitor array needs to be closed. Therefore, the input signal is compared with a specific voltage first, and according to the comparison result, the off state of the lock switch is judged. If the lock switch is open, the single-ended SAR ADC carries out normal analog-digital conversion. If the lock switch is closed, the capacitor connected with the lock switch in the capacitor array of the single-ended SAR ADC will be locked and kept connected to GND. When the input signal is small, by closing the lock switch, the high-order capacitor is locked, the unnecessary switching of the capacitor array is reduced, and the power consumption of the capacitor array and the switch can be greatly saved at the cost of less hardware overhead.
