IBIAS Monitor Accuracy Calculations

IBIAS (mA)

Figure 40. Accuracy of IBIAS to IBMON Ratio

This example assumes that the nominal value of IBIAS is 8 mA

and that the IBIAS range for all operating conditions is 4 mA to

14 mA. The accuracy of the IBIAS to IBMON ratio is given in

the Table 1 and is plotted in Figure 40.

Referring to Figure 40, the IBMON output current accuracy is

±4.3% for the minimum IBIAS of 4 mA and ±3.0% for the

maximum IBIAS value of 14 mA.

The accuracy of the IBMON output current as a percentage of

the nominal IBIAS is given by

100

MIN

Accuracy

IBMON

for the minimum IBIAS value, and by

100

MAX

Accuracy

IBMON

for the maximum IBIAS value. This gives a worse-case accuracy

for the IBMON output current of ±5.25% of the nominal IBIAS

value over all operating conditions. The IBMON output current

accuracy numbers can be combined with the accuracy numbers

for the 750 Ω IBMON resistor (RIBMON) and any other error

sources to calculate an overall accuracy for the IBMON voltage.
