. (8) Externally adjustable
to zero error. (9) Differential non-linearity error at bipolar major carry input code. Externally adjustable to zero error. (10) Full scale range (5.50V). (11) Refer to equivalent
circuit in Figure 1. (12) Worst case operating condition. Refer to typical performance curves.
