This line is noise source. But if power line

and GND are divided into two, this line

becoms AVDD,AGND

Please take care this Power line. Because this line is most weak

indigitalnoise. So this line must be separated from digital_VDD,

GND. And place bypass capacitor (0.01

µF) for power pin as close

to BU2370FV as possible.

This line is most noise source. So it should be separated from Analog.

And this line should be connected VDD of external VCC-outdivide.

And place bypass capacitor (0.01

µF) for power pin as close to

BU2370FV as possible.

DVDD,DGND

And place bypass capacitor (0.01

µF) for power pin as close to

BU2370FV as possible.

∗Recommend to control (FSEL1, PDE, VCOE) by power line.(DVDD, DGND)

∗Recommend to use capacitor that is better to reduce high frequency noise.
