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 of 100 µF is necessary to minimize
the power supply noise in low frequencies. For better quality bypassing, we recommend
adding a CMS 100 nF capacitor, also placed as close as possible to the IC pins.
