configuration
The current sensing configuration allows monitoring of the current that is consumed by an
application. On this expansion board, the operational amplifier is set to a high-side current
sensing structure. This means that the current is measured close to the supply voltage, thus
before the application.
Figure 3
illustrates this concept.
