We're facing a issue that the analog input is instability below.
CH4 is IN+. CH3 is SDO.
Actually the driver amp is OPA197 (Ti), we recommend ADA4084-1 instead of Ti.
But the customer say if the instability is not improved within this week, he may use ADS8863 (Ti) instead of AD7688.
The input+ is DC voltage and the input- is GND as single input.
Could you please give me any advice.
Thank you very much in advance.
