3.1 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.
