1. What is ADC for data acquisition?
A data collector is an electronic device used to convert various data (such as barcodes, RFID tags, etc.) into a storable and editable format and transmit it to a computer or system in real time. Data collectors are usually operated using handheld devices (such as inventory counting machines or PDAs) and have functions such as real-time acquisition, automatic storage, instant display, instant feedback, automatic processing, and automatic transmission. They can be widely used in warehouse management, logistics transportation, retail, medical, military and other fields. The main functions of data collectors include data acquisition, real-time data processing, data storage and transmission.
ADC, or analog-to-digital converter, is an electronic device that can convert continuously changing analog signals into discrete digital signals. It is mainly used in data acquisition, signal processing, communication and other fields.

2. 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.

3. 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 -
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
