〈C pin〉
In order to connect a capacitor capable of smoothing the pin voltage to the C pin, the correlation given in the following
equation must be satisfied when f (Hz) serves as the input frequency of the CTL pin. (R is incorporated inside the IC,
and it is 180kΩ (typ.).)
1/f = t < CR
The higher the capacitance of the capacitor, the slower the response to changes in the input signals.
