This calculator is for an active noninverting op amp low pass filter. This op amp low pass filter produces a noninverting signal at the output. This means that the output signal is exactly in phase with the input signal. Resistor R and capacitor C set the cutoff frequency point. ...

Inverting Op Amp:ACL= - RF/R2= - VOUT/VIN(Equation 1) Non-Inverting Op Amp:ACL= 1 + (RF/R2) = (VOUT/VIN)(Equation 2) where ACLis the closed-loop gain, RFis the value of the feedback resistor and R2is the value of the resistor from the negative input terminal to signal (inve...
The active RC filter, with either BP or LP characteristics has a first operational amplifier (OV1) connected at its output to the inverting input of a second op. amp. (OV2) whose own output is connected back either via a capacitor (C1) or a resistor to its inverting input. The second...
Combining R3 with C2 forms a low-pass filter with a corner frequency of approximately 500 Hz. This is needed to maintain amplifier PSRR, since the supply is connected to VIN through the input divider. The values for R2 and C2 were chosen to demonstrate the AD818's exceptional output drive...
