| What are the important technical indicators of the successive approximation analog-to-digital converter? |
* Answer
| 1) Resolution, which is the A/D conversion accuracy, which depends mainly on the minimum quantization unit for setting the digital.The more digital digits of the A/D output, the smaller the minimum quantization unit, the higher the resolution, the smaller the rounded error of the converted digital, and the higher the A/D conversion accuracy.The function of the digital-to-analog converter is to convert the digital quantity into a corresponding analog voltage output through a decoding circuit.The size of the digital quantity is expressed in a binary combination of bit weights.The size of each bit whose number is l is the weight of the bit.Adding all the bit weights of l to the weight represents the size of this number. |
