Customer encountered several problems when using ADS1298. Please give some suggestions. The problems are as follows.
1.In July 06, 2019, a total of 187 people were tested in the company. Half of them had problems of big interference and steps.
Appendix is the waveform with larger interferenceADS1298 noise.docx
2. In production debugging, ADS1298 input connect to GND, and then test the output. It is found that some chips have high interference noise.
3. Because of the poor uniformity ,They hope that every chip manufactured will test noise, test time 10-20s, output noise amplitude < 3uVpp, minimum CMRR > 110dB.
