Hi,

In AD7960, Gain Error is mentioned as +30 LSB. Is this error at Full Scale Voltage or in the middle ? Is Max gain error always at the Full Scale Voltage or It can be in the middle also.? Can somebody clarify this question?

Thanks in Advance

Hi,

The gain error is defined on page 13 of the datasheet as “the deviation of the difference between the actual level of the last transition and the actual level of the first transition from the difference between the ideal levels.” The +30 LSB spec is from fullscale. We can look at gain error as the amount by which the actual slope of the figure below differs from the ideal.
