APPLICATION INFORMATION (continued)
Most applications require a ferrite bead filter. The ferrite filter reduces EMI around 1 MHz and higher (FCC and
CE only test radiated emissions greater than 30 MHz). When selecting a ferrite bead, choose one with high
impedance at high frequencies, but low impedance at low frequencies.
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.
When both an LC filter and a ferrite bead filter are used, the LC filter should be placed as close as possible to
the IC followed by the ferrite bead filter.
Figure 22. Typical LC Output Filter, Cutoff Frequency of 27 kHz, Speaker Impedance = 8
Figure 23. Typical LC Output Filter, Cutoff Frequency of 27 kHz, Speaker Impedance = 4
