Analog to digital Converters (ADCs) are electronic devices used to convert continuously varying Analog signals into discrete Digital signals. This process usually includes three steps: sampling, quantization and coding. Sampling means capturing the instantaneous value of an analog signal at a fixed frequency; Quantization approximates these transient values to the nearest discrete level; Finally, the encoding converts the quantized value into binary numeric form.

ADCs（Analog-to-digital Converters） is widely used in a variety of scenarios, such as audio and video recording, measuring instruments, wireless communications, medical devices, and automotive electronics. For example, in audio devices, the ADC is responsible for converting the sound signal captured by the microphone into a digital format for easy storage and transmission.

• 1. How many types of ADC are there?

  The types of ADC (Analog-to-Digital Converter) mainly include:
  1. Integral ADC: Its working principle is to convert the input voltage into time (pulse width signal) or frequency (pulse frequency), and then obtain the digital value by the timer/counter. The advantage of the integral ADC is that it can obtain high resolution with a simple circuit and has strong anti-interference ability, but the disadvantage is that the conversion rate is extremely low because the conversion accuracy depends on the integration time.
  2. Successive approximation type (SAR ADC): The successive approximation ADC is one of the most common architectures. Its basic principle is to convert by gradually approximating the value of the analog input signal. The advantages of the successive approximation ADC are high speed and low power consumption. It is cheap at low resolution, but expensive at high precision.
  3. Parallel comparison type/serial-parallel comparison type ADC: The parallel comparison type AD uses m

• 2. How to convert analog to digital without ADC?

  Analog to digital conversion without ADC can be achieved through PWM circuit. This method is suitable for those main control chips without built-in ADC, which needs to be solved by two GPIOs and an operational amplifier. The basic principle is to use an integral circuit to convert the PWM wave into a smooth DC voltage, and then continuously adjust the PWM duty cycle by comparing it with the voltage to be measured until the output of the comparator changes from 0 to 1, and record the current PWM duty cycle, thereby realizing the measurement of the analog voltage.

• 3. What is the difference between the input and output of an ADC?

  The input of ADC (Analog-to-Digital Converter) is analog quantity and the output is digital quantity.
  The main function of ADC is to convert continuous analog signal into discrete digital signal. In electronic systems, analog signal usually refers to continuously changing voltage or current, such as the signal obtained from microphone or sensor. The amplitude and frequency of these analog signals can change continuously, while digital signals are composed of a series of discrete values, usually expressed in binary form.
  Input: The input of ADC receives analog signals, which can be in the form of continuously changing physical quantities such as voltage and current. The amplitude and frequency of analog signals can change continuously, such as the voltage range from 0V to 5V.
  Output: The output of ADC is digital signal, which is composed of a series of discrete values, usually expressed in binary form. The advantage of digital signals is that they can be calculated and processed quic
