9 Power Supply Recommendations

To decouple the LMP92064 from AC noise on the power supply, it is recommended to use a 0.1-μF bypass capacitor between the VDD and GND pins. This capacitor should be placed as close as possible to the supply pins. In some cases an additional 10-μF bypass capacitor may further reduce the supply noise. In addition, the VDIG power pin should also be decoupled to DGND with a 0.1-μF bypass capacitor. Do not forget that these capacitors must be rated for the full supply voltage (2x the maximum voltage is recommended for the capacitor working voltage rating).
