Use an LC output filter if there are low frequency
(<
1 MHz
EMI sensitive circuits and/or there
are long wires from the amplifier to the speaker. EMI is also affected by PCB layout and the
placement of the surrounding components.
The suggested LC values for different speaker impendence are showed in following figures for
reference.
