Sallen-Key Low-Pass Filter Calculator

This is a second-order, Sallen-Key Low-Pass Filter Calculator, Set the desired cutoff frequency, Q factor to generate resistor and capacitor values, then adjust the bode plot max frequency to view the response over the desired frequency sweep.

Bandwidth (BW): Hz

A technical schematic for a 6-channel Sallen Key Low Pass Filter. The page features six identical active filter circuits arranged in two columns, labeled VIN1 through VIN6. Each circuit utilizes an MCP601T op-amp with varying capacitor and resistor values to achieve specific -3dB cutoff frequencies ranging from 100 Hz to 10 MHz.
