Hi,

 

We are trying to design the external reference for above mentioned ADC. This design is given by my expert.

 

The circuit of ADC as well as its external reference has been attached in this email and has been given by my expert but I am short of data in order to verify the correctness of the design.

 

I will request this intelligent community to please let me know how to verify this design and whether we are on right track or not. I have seen many a times that references do not behave properly [has ripple which causes conversion inaccuracy] based on the throughput of the requirement of the ADC and again adding more capacitance does not solve the issue as it provides instability to opamps at times.

 

View of experts here will matter a lot and will be thankful for it.

 

I have attached the schematic in pdf for ready reference.

 

Best Regards.
