is extrapolated from measurements for the gain-error test.

8. For V

> 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and used.

9. Gain or transconductance error is calculated by applying two values of V

and calculating the error of the slope vs. the ideal.
