The both ends of the feedback resistor RF are connected to feedback capacitor CF in parallel, it is used to compensate for the feedback resistor, RG input equivalent capacitance and the effect on high - frequency signal from circuit board stray capacitance, so that the circuit has the best fast settling time. Output ( 6 feet ) end is connected to Rx, CL to reduce high-frequency noise, CIN is equal to INA321/322 input capacitance ( 3pF) and stray capacitance. RIN · CIN = RF · CF.
