TPA0132
SLOS223E – MAY 1999 – REVISED SEPTEMBER 2004
Figure 30 and Figure 31 are schematic diagrams of typical notebook computer application circuits.
NOTE: A 0.1-F ceramic capacitor should be placed as close as possible to the IC. For filtering lower-frequency noise
signals, a larger electrolytic capacitor of 10 F or greater should be placed near the audio power amplifier.
