10.1 Layout Guidelines

To properly bypass the power supply, several locations on a printed-circuit board must be considered. A 6.8-µF or greater tantalum capacitor must be placed at the point where the power supply for the amplifier is introduced onto the board. Another 0.1-µF ceramic capacitor must 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 requires a bypass with a 0.1-µF capacitor. If the amplifier is operated in a dual power supply, both V⁺ and V^– pins must 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.
