The wiring of op-amp applications circuit inputsThe impedance of Op amp's inverting input and the non-inverting inputare high, the input wiring should be short, otherwise, the external electrostatic and electromagnetic induction will generate noise. Figure is the in-phase amplifier circuit with phase gain of 40dB; the impedance of inverting input is high, if the wiring of this part is too long, which will lead to noise.So feedback resistor RF and Rs should be connected close to the inverting input to make the part of the high-impedance bea short connection.
