Low-Cost, SOT23, Voltage-Output,
High-Side Current-Sense Amplifier
amp’s supply voltage range should be at least as high
as any voltage the system may encounter.
The percent error introduced by output loading is
determined with the following formula:
where RLOAD is the external load applied to OUT.
Current Source Circuit
Figure 3 shows a block diagram using the MAX4173
with a switching regulator to make a current source.
