2. The voltage gain (Gfg) of the FG amplifier is determined by the following formula. Here Rfgf is
the internal feedback resistance. See the electrical characteristics table.
However, note that R103 must be equal to R104.

4. The PWM carrier frequency is determined by the following formula. Here VR1 and K are the
charge pump voltage and the oscillator amplitude (see the electrical characteristics table),
respectively.

5. The FG amplifier bandwidth BW is determined by the following formula. Here Rfgo is the pin 15
output resistance. See the electrical characteristics table.
However, when C105 is 0, BW is limited to 8 kHz by the internal capacitance.

(Vp-p) or higher is applied, irregular rotation may occur due to FG amplifier
saturation.
9. The absolute value of the whole amplifier input voltage must be within the in-phase input voltage
range.
10.This should be decided after consultation with the oscillator manufacturer.
