Hello

Vin=3.3V, Table2 recommend fco=7.8KHz,my customer select below parameter, so if it is suitable ? how much the range of fco?

R1130kΩ(±0.1%)

CFF150pF(±5%)

Fco8.16kHz(typ)7.42kHz(min)^8.22kHz(min)

  • Hi Fandy,

    Your circuit is approx. +/-5% tolerance from 7.8KHz and it is ok to use these values in this circuit.

    Kind Regards,
