Figure 46. Ferrite chip bead placement
In the case where the distance between the TS2012 output and the speaker terminals is too
long, it is possible to have low frequency EMI issues due to the fact that the typical operating
frequency is 280kHz. In this configuration, it is necessary to use the output filter represented
in
