6. Output current characteristic measured with low impedance ammeter connected to GND

7. Defined as difference between actual output current and 40µA; measured at V

SENSE

=10mV. This will include an error due to bias

currents of the device.

8. For V

SENSE

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