6) Y filter
With the BU1425AK / AKV, the frequency characteristic
of Y, which is mixed with the VOUT pin output, is set so
BU1425AK / BU1425AKV
that it can be selected using the YFILON1B and 2B pins.
A through filter is normally used on the YOUT pin output,
so that it is not limited to this method.
