TPA6011A4
SLOS392A – FEBRUARY 2002 – REVISED JULY 2004
Figure 28 and Figure 29 are schematic diagrams of typical notebook computer application circuits.
A. A 0.1-µF ceramic capacitor should be placed as close as possible to the IC. For filtering lower-frequency noise
signals, a larger electrolytic capacitor of 10 µF or greater should be placed near the audio power amplifier.
