(1) Offset is extrapolated from measurements of the output at 20 mV and 100 mV V_SENSE.

(2) Total output error includes effects of gain error and V_OS.

(3) Linearity is best fit to a straight line.

(4) For details on this region of operation, see the Section 7.4.2 section in the Section 8.

(5) See Typical Characteristic curve Positive Output Voltage Swing vs. Output Current (Figure 6-8).

(6) Specified by design; not production tested.
