10.1 Layout Guidelines

To properly bypass the power supply, several locations on a printed circuit board need to be considered. A 6.8 µF or greater tantalum capacitor should be placed at the point where the power supply for the amplifier is introduced onto the board. Another 0.1-µF ceramic capacitor should be placed as close as possible to the power supply pin of the amplifier. If the amplifier is operated in a single power supply, only the V+ pin needs to be bypassed with a 0.1-µF capacitor. If the amplifier is operated in a dual power supply, both V+ and V− pins need to be bypassed. It is good practice to use a ground plane on a printed-circuit board to provide all components with a low-inductive ground connection.
