1. What are DAC and ADC?
ADC and DAC are two important concepts in digital electronics. ADC stands for "analog-to-digital converter", which can convert analog signals into digital signals. DAC stands for "digital-to-analog converter", which can convert digital signals into analog signals. Both converters play an important role in many electronic products, such as mobile phones, televisions, stereos, etc.

2. What is analog data acquisition?
Analog data acquisition refers to the process of converting continuously changing signals of physical quantities into digital signals so that computers can process and record these signals. This process involves the use of an analog quantity collector, which is a hardware device that can convert analog signals of physical quantities into digital signals and then transmit them to a computer for processing and recording.

3. 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.

4. What is the principle of analog-to-digital converters?
The working principle of the analog-to-digital converter (ADC) is to convert analog signals into digital signals through four processes: sampling, holding, quantization, and encoding.
The main components of the analog-to-digital converter include samplers and quantizers, which work together to convert continuous analog signals into discrete digital signals. This process requires a reference analog quantity as a standard, and the maximum convertible signal size is usually used as the reference standard. The basic principles of the analog-to-digital converter can be summarized as follows:
Sampling: The analog-to-digital converter first samples the input analog signal through a sampling circuit, that is, discretizes the analog signal on the time axis.
Holding: The sampled signal is held by the holding circuit for the next quantization and encoding process.
Quantization: The quantization process is to divide the amplitude of the sampled and held analog signal into a finite number of le
