The dac settle time is almost constant, no matter how large is the amplitude, for the asysar adc ,the dac cap is very small. But the comp need long time settle a correct output when the input amplitude is small, so the delay time for the dac settle time can be a fixed one. The different amplitude which impact the compare time is realized by the comp. |
