For example, consider an application in which the TPA3001D1 drives an 8-
speaker from an 18-V power
supply. The maximum output power with no distortion (less than 1% THD) is 16 W, which corresponds to a
maximum peak output voltage of 16 V. For the same output voltage level driven into clipping (10% THD), the
output power is increased to 20 W.
OUTPUT FILTER CONSIDERATIONS
A ferrite bead filter (shown in Figure 34) 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 35 and Figure 36.
