Place the 0.1 mF capacitor within 0.1 inches of the power pin. It is important to place the ceramic capacitors within 0.1 inches of the power pins. As the distance increases, the capacitor becomes less effective because of the added trace inductance. An example for a single supply amplifier is shown in Fig. If a dual supply amplifier is used, simply include the same bypass capacitors for the other rail.
Some amplifiers have minimum stable gain requirements.
If an amplifier is used at gains lower than the recommended minimum stable gain, it could oscillate. Do not use a capacitor or other non-linear element in the amplifier's direct feedback loop. Eliminate long lead lengths or use surface-mount components. Place the bypass capacitors as close as possible to the supply pins. A design rule for the specific amplifier has been broken.
