(1)Offset Error is the measured deviation of the midscale transition from the ideal midscale transition.
(2)Gain Error is the difference between the nominal and actual offset point on the transfer function after the offset error has been corrected to zero.
The gain point is the mid-step value when the digital output is full-scale.
(3)Average switching current drawn from external reference. DC component of current is internally generated even in external reference mode.
