Op-Amp Calculator

Op-Amp RC Low-Pass Filter Calculator

Calculate RC low-pass filter cutoff frequency for op-amp input or feedback filtering.

Op-Amp RC Low-Pass Filter Calculator Formula

fc = 1 / (2 x pi x R x C)

Useful for sensor interfaces, ADC front-ends, audio circuits, filters and precision analog design.

Design note

Always check op-amp input/output voltage range, supply voltage, bandwidth, slew rate, noise and stability with real component values.
