TPA0142
SLOS248E – JUNE 1999 – REVISED SEPTEMBER 2004
APPLICATION INFORMATION (continued)
A.
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.
