One of my customer is now calculating maximum DC error of AD7607 ADC.
The data sheet indicated the “Positive/Negative Full-Scale error with external reference is +/-2LSB typ and +/-9LSB max.
On the other hand, it says only +/-2LSB typ with internal reference condition.
My customer needs rough number for max error with internal reference.
He will accept not guaranteed max error number, he need it for his error allocation calculation in his system.
Thank you for your help.
