NOTES: A. This connection is for ultra-low current in shutdown mode.
B. 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.
