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 1

µF is necessary to minimize the distortion.

For better quality bypassing, a capacitor of 10nF can be added using the same implementation

conditions. Bypass capacitors must be incorporated for both the negative and the positive

supply.
