Data Sheet
The value of K depends on the actual resistance of the TOSA
and can be obtained from Figure 35. For a TOSA resistance of
12 ?, the typical value of K is 110 mA/V. Assuming that I MOD =
40 mA and using the preceding equation, the MSET voltage is
given by
ADN2531
This example assumes that the nominal value of I BIAS is 40 mA
and that the I BIAS range for all operating conditions is 10 mA to
Referring to Figure 41, the IBMON output current accuracy is

±4.3% for the minimum I BIAS of 10 mA and ±3.0% for the
maximum I BIAS value of 80 mA.

The MSET voltage range can be calculated using the required
I MOD range and the minimum and maximum K values. These
values can be obtained from the minimum and maximum

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.
