Care must be taken when choosing the right resistor for current measurement application. Note that
because of the 10× amplification, the maximum measurable difference between the AV and AC pads is

resistor appropriately.
ranges. When choosing resistor values for a system, there is a trade-off between measurement accuracy
and power consumption. Choosing a large resistor will increase the voltage drop and hence increase
accuracy of the measurement; however the larger voltage drop dissipates more power (P = I
The Current Monitor is a unipolar system, meaning that the differential voltage swing must be from 0 V to
V
than 0 V. This results in the requirement that the potential of the AV pad must be larger than the potential
of the AC pad. This is straightforward for positive voltage systems. For a negative voltage system, it
means that the AV pad must be "more negative" than the AC pad. This is shown in
In this case, both the AV pad and the AC pad are configured for negative operations and the output of the
differential amplifier still falls between 0 V and V
