Webunder test. In the case of DAC testing, the digitizer in the DVM must be at least 10 times more linear than the DAC under test. If the INL of the DAC is at the +/-2 LSB level, then the digitizer’s non-linearity must be in the range of +/-0.2 LSB. This stringent requirement on the linearity means that a highly WebThe Integral Non-Linearity is defined as the maximum deviation of the ADC transfer function from the best-fit line. An ADC function is to digitize a signal into a stream of digital words called samples. The ADC output is discrete as opposed to the input, which is continuous. It is used at the boundary between the analog and digital realms. flagstaff bus stationWebMay 6, 2024 · I used DAC levels from 20 to 4075 to avoid zero offset errors at low voltages and DAC buffer problems at high voltages.
