OUTPUT FILTER CONSIDERATIONS
SLOS418D – SEPTEMBER 2003 – REVISED MARCH 2008
Figure 15. The TPA3007D1 Output Voltage and Current Waveforms Into an Inductive Load
The output of the TPA3007D1 may be driven into clipping to attain a higher output power than is possible with no
distortion. Clipping is typically quantified by a THD measurement of 10%. The amount of additional power into
the load may be calculated with Equation 1.
A ferrite bead filter (shown in Figure 16) should be used in order to pass FCC and/or CE radiated emissions
specifications and if a frequency sensitive circuit operating higher than 1 MHz is nearby. 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 very low impedance at low frequencies.
Use an additional LC output filter if there are low frequency (<1 MHz) EMI sensitive circuits and/or there are long
wires (greater than 11 inches) from the amplifier to the speaker, as shown in Figure 17.
