**Part Number:**ADC10080

Hi Team, seeking for some assistance.

We need to know how much gain error we may expect from ADC10080 in our design.

In our design, ADC's input is drived by a ADA4930-1 differential amplifier. ADC's input signals are symetric around an identical VOCM DC voltage.

In ADC10080's datasheet page 6, Gain Error (GE) is specified for Positive Error and Negative Error, with min/max values of -1.6/+2.0 %FS.

We believe "Positive Error" means "for Vin+ input" and "Negative Error" means "for Vin- input", so we get error for individual inputs. Is it right?

If this is right, we need to know the differential gain error (Vin+ - Vin-) for our application. Are Vin+ and Vin- individual gain error quite the same, such that differential gain error tends to be close to 0%FS? Any value to provide about differential gain error?

Else, can Positive Error and Negative Error be opposed for a same part (let say Vin+ at +2.0 %FS while Vin- at -1.6 %FS for example) leading to a worst case total error close to 4% FS?

Thank you in advance.
