Timming of AD conversion

Hi NathanT  

Could you or your team please help look into this query?

Thanks,

Coco

Hi, atsuo130 .

Thank you for your patience. How is thread going? Have you resolved it?

Let's try diving into this query:

1) What is your application?

2) What do you mean by switching the input? Do you have a source that has a switching mechanism? 

3) Are you just using the R1_IN? What is your input signal?

4) Are you using the internal or external clock?

  4.1) If internal clock, during the conversion a 16-bit word will be shifted out MSB-first on the DATA pin. This word represents the result from the previous conversion. The question is, when did you change the input signal? Is it within the 2.7 us? Or does your data cover beyond the 2.7 us?  If that is the case, the data that is remaining during the transition from conversion to acquisition phase is the only data that will be converted. 

  4.2) If external, what mode are you configured? 

  4.3) I highly suggest changing your input during the acquisition phase. Changing during the conversion phase is not guaranteed as the switches are disconnected at the input. 

Warm regards,
Jo
