Other Parts Discussed in Thread: ADS131A04
I just have finished the design of ADS131a04. The general design is as follows:
I can use the dc source(Source Accuracy at 1mv) to evaluate the ADC. However, due to the signal source accuracy problem, I can't get the actual accuracy of ADC. just sotp at the mv level.
So tell me, what signal source do you use to evaluate ADC? please give me the definite element or equipment.
What device is used to measure buffer output? high precision multimeter? or oscilloscope?
Is there some complete test plan?
