Worst case error on 10 V range
Error = ((8 ppm × 10.0 V) + (0.05 ppm × 10.0 V)) + (1 ppm × 10.0V) + 5((0.15 ppm
× 10.0 V) + (0.01 ppm × 10.0 V))
= 98.5 μV
Percentage Error = 0.000985%
Worst case error on 15.8 V maximum power setting
Error = ((10 ppm × 15.8 V) + (0.3 ppm × 100.0 V)) + (0.5 ppm × 15.8 V) + 5((0.15
ppm × 15.8 V) + (0.1 ppm × 100 V))
= 257.75 μV
