ADN2530
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

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
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 ? IBMON resistor (R IBMON ) and any other error
sources to calculate an overall accuracy for the IBMON voltage.
