1. How to perform digital-to-analog conversion?
The digital-to-analog conversion process is to convert a digital signal into a continuously changing analog signal. This is usually achieved through a weighted resistor network or an R-2R ladder network, where each bit controls a switch that determines whether the corresponding voltage is added to the final output.

2. What is the difference between an ADC and a DAC?
An ADC converts a continuously changing analog signal into discrete digital values, while a DAC performs the opposite operation, converting the digital value back into a continuously changing analog signal.
-
3. Which ADC converter requires a DAC in its architecture?
The successive approximation register (SAR) type ADC includes a built-in relatively simple DAC. It is used to compare with the input analog signal to determine the corresponding digital code.

4. What are ADC and DAC in Arduino?
On Arduino boards, ADC usually refers to the analog-to-digital converter integrated in the microcontroller, which is used to read the values of analog sensors. However, not all Arduino boards directly support DAC. For those Arduino boards that do not directly support DAC, an external DAC module may be required to achieve the digital-to-analog conversion function.
