Note:1. This connection is for ultra-low current in shutdown mode.

2. A 0.1 µF ceramic capacitor should be placed as close as possible to the IC.For filtering lower-

frequency noise signals, a larger aluminum electrolytic capacitor of10 µF or greater shouldbe

placed near the audio power amplifier.
