Other Parts Discussed in Thread: OPA625
Hello,
When using 10 ADS8861s on the same board with REF60xx, can one REF60xx be shared with all 10 ADS8861s?
Or each ADS8861 requires each separated REF60xx?
Regards,
Oba

Hello Oba-san,
Each ADS8861 needs its own reference driver buffer. You could use 10 REF60xx, but I would suggest using 1 REF50xx for a single system reference voltage, and then provide a buffer for each ADS8861.
For the reference buffer, if the DC accuracy is good enough, the OPA625 would work very well.
