4 Power Supply Considerations

Correct power supply bypassing is very important for optimizing performance in high-frequency ranges.

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, a capacitor of 10nF is added using the same implementation conditions. Bypass capacitors

must be incorporated for both the negative and the positive supply. On the SO8_SINGLE_HF board,

these capacitors are C8 and C6.
