Op-Amp Voltage and Gain Calculator

Non-Inverting Op Amp Gain

non_inv_amp_cir_dia
\( V_{out} = A \cdot V_{input} \)
where \( A \) is the Gain
\( A = 1 + \frac{R_2}{R_1} \)

Inverting Op Amp Gain

inv_amp_cir_dia
\( V_{out} = A \cdot V_{input} \)
where \( A \) is the Gain
\( A = -\frac{R_2}{R_1} \)

For an inverting op-amp, the negative sign means the output voltage inverted compared to the input. Positive input results in a negative output, and negative input results in a positive output.
