Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

is extrapolated from measurements for the gain-error test.
Gain error is calculated by applying two values of V
SENSE
and calculating the error of the slope vs. the ideal:
Gain = 25, V
SENSE
is 20mV and 120mV.
