Non-Inverting Op-Amp Resistor Calculator
See our other Engineering
This calculator determines the bias and feedback
resistors for a non-inverting op-amp, given the gain and desired output bias point.
There are many free parameters to the design so enter the value of R1, which
will scale the other resistors. Use V1 as the input for the inverting
Op-Amp, and V2 as a voltage offset if needed. Set V2 to zero if no
offset is required.
To use the calculator
you first need to determine the desired gain of the ac signal, and the quiescent
output voltage (the value when the AC input signal is zero).
injects a non-zero V2 voltage component into the circuit and correspondingly
offset Vout. Another way of looking at it is, if V2 is zero and the DC
component of V1 is zero then Vout will also be zero. The amplified
output signal will ride on the quiescent output voltage.
