Power supply considerations

Correct power supply bypassing is very important for optimizing performance in

high-frequency ranges. The bypass capacitors should be placed as close as possible to the

IC pins to improve high-frequency bypassing. A capacitor greater than 10 µF is necessary to

minimize the distortion. For better quality bypassing, we recommend adding a 10 nF

capacitor, also placed as close as possible to the IC pins.
