POWER SUPPLY DECOUPLING

In order to decouple the LMP8480/81 from AC noise on the power supply, it is recommended to use a 0.1

μF

supply pins. In some cases an additional 10

μF bypass capacitor may further reduce the supply noise.

Do not forget that these bypass capacitors must be rated for the full supply and/or load source voltage! It is

recommended that the working voltage of the capacitor (WVDC) should be at least two times the maximum

expected circuit voltage.

LLP DIE ATTACH PAD

The bottom thermal pad of the LLP package should be tied to the same ground as the ground pin. Be aware that

noise on this pad can couple into the bottom of the die, so the ground should be as clean as possible.
