Worst case error on 0.1V range:
Worst case error on 1V range
Worst case error on 10V range
Voltage Error Distribution Standard Uncertainty
2.375uV Rectangular 1.371uV
Voltage Error Distribution Standard Uncertainty
10.55uV Rectangular 6.09uV
Voltage Error Distribution Standard Uncertainty
98.5uV Rectangular 56.8uV
Error = ((9ppm x 100mV) + (3ppm x 100mV)) + (6ppm x 100mV) + 5((0.15ppm x 100mV) + 100mV))
= 2.375uV
Percentage Error = 0.002375%
Error = ((8ppm x 1.0V) + (0.3ppm x 1.0V)) + (1ppm x 1.0V) + 5((0.15ppm x 1.0V) + (0.1ppm x 1.0V))
= 10.55uV
Percentage Error = 0.001055%
Error = ((8ppm x 10.0V) + (0.05ppm x 10.0V)) + (1ppm x 10.0V) + 5((0.15ppm x 10.0V) + (0.01ppm x 10.0V)
)
= 98.5uV
Percentage Error = 0.000985%
