Power supply considerations

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 of 100µF is necessary to minimize the

power supply noise in low frequency. For better quality bypassing, we recommend to add a

CMS 100nF capacitor, also placed as close as possible to the IC pins.
