(2) Total output error includes effects of gain error and VOS. (3) Linearity is best fit to a straight line. (4) For details on this region of operation, see the Accuracy Variations as a Result Of VSENSE and Common-Mode Voltage section in the Application and Implementation. (5) See Typical Characteristic curve Positive Output Voltage Swing vs Output Current (Figure 8).
