The gain error of an ADC indicates how well the slope of an actual transfer function matches the slope of
the ideal transfer function. Gain error is usually expressed in LSB or as a percent of full-scale (%FSR).
Gain error is the full-scale error minus the offset error

Gain-error drift is the variation in gain error due to a change in ambient temperature, typically expressed
in ppm/°C.
