For a full Radiated Emissions report, please contact your local TI representative.
For operation with a resistor – speaker load configuration the ferrite bead filter can often be used if the design is
failing radiated emissions without an LC filter and the frequency sensitive circuit is greater than 1 MHz. This filter
functions well for circuits that just have to pass FCC and CE because FCC and CE only test radiated emissions
greater than 30 MHz. When choosing a ferrite bead, choose one with high impedance at high frequencies, and
very low impedance at low frequencies. In addition, select a ferrite bead with adequate current rating to prevent
distortion of the output signal.
Figure 22 shows a typical ferrite bead output filter.
