TPA6021A4
SLOS465 – JUNE 2005
Figure 19 and Figure 20 are schematic diagrams of typical LCD monitor application circuits.
A. A 0.47-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.
