Worst case error on 0.1 V range:
Error = ((9 ppm × 100 mV) + (3 ppm × 100 mV)) + (6 ppm × 100 mV) + 5((0.15 ppm
× 100 mV) + 100 mV))
= 2.375 μV
Percentage Error = 0.002375%
Worst case error on 1V range
Error = ((8 ppm × 1.0 V) + (0.3 ppm × 1.0 V)) + (1 ppm × 1.0 V) + 5((0.15 ppm × 1.0
V) + (0.1 ppm × 1.0 V))
= 10.55 μV
Percentage Error = 0.001055%
