2

This is the supply bypass capacitor. It provides power supply filtering. Refer to the

Application Information

section for proper placement and selection of the supply

bypass capacitor.

3

This is the BYPASS pin capacitor. It provides half-supply filtering. Refer to the section,

Proper Selection of External Components

, for information concerning proper

4

This is the output coupling capacitor. It blocks the DC voltage at the amplifier’s output
