Analog-to-digital conversion circuit, digital-analog hybrid chip having the same, electronic device, vehicle

Abstract

The application relates to the technical field of electronic appliances, and provides an analog-digital conversion circuit, a digital-analog hybrid chip with the same, electronic equipment and a vehicle. The analog-digital conversion circuit comprises a voltage selection module, a comparison module and an encoding module. The voltage selection module can sequentially output different analog voltages to the comparison module. The comparison module can output a digital signal to the encoding module according to the comparison result of the analog voltage and a reference voltage, so that the encoding module can convert the digital signal to obtain a conversion result. The analog-digital conversion circuit provided by the application can greatly reduce the chip area and simultaneously greatly reduce the power consumption.
