![]() To sum it up, the 12-bit ADC has higher accuracy than the 8-bit ADC. On the other hand, a 12-bit ADC will convert its input voltage into 4095 digital values. The input voltage for an 8-bit ADC can be converted into 255 digital values which are the result of 2 n−1. An 8-bit resolution ADC has different accuracy from a 12-bit resolution ADC. It determines the accuracy level of the ADC. This is the benefit of a fast sampling rate. To get the information on the sampling rate, one must check the related datasheet.Ī high sampling rate helps you to pick sudden peak data properly, while the lower one is not able. The unit to show the sampling rate is SPS (sample per second). It defines the conversion speed of analog to digital the ADC can do every second. While Vin is the analog data from nature (measured by a sensor), Vref is the reference voltage, and Max of digital data is the maximum number of digital data in the coding process. The formula can be described as the following:ĪDC digital data = (Vin/Vref) x Max of digital data ![]() ![]() It is a voltage required to act as the reference in calculating the digital data. The following features are best for you to understand before you go deeper about ADC. The ADC circuits can be found as a stand-alone ADC IC module or embedded into microcontrollers. ![]() An ADC (analog to digital converter) is an electronic circuit that converts the analog data (continuous) from nature into digital data (binary).
