Doc ID 16263 Rev 1

The C2 capacitor is optional and can be used if additional filtering is required, with typical

values of 47 to 220 nF.

The STC3100’s ground connection (GND) is used as the reference input for the current

measurement and must be connected to the ground side of the sense resistor by a

dedicated track. No current, except the supply current of the STC3100 itself, must flow in

this track to avoid creating an offset error in the current measurement.
