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 of 10 μF or greater should be

placed near the audio power amplifier.
