BA6386K
RFO is shifted downwards from VB by 0.9V.
However, the resistance between pins 23 and 24 is set
to 20kΩ and if this resistance is changed, use external
components to adjust the shift back to 0.9V. Have the
feedback resistance 10kΩ or greater.
If the DC component of RF rises 0.3V, then FOK be-
comes high.
