Working Principles

The MAX7427EUA+T is an 8th order low-pass filter that utilizes a Butterworth response. It operates by attenuating frequencies above the cutoff frequency while allowing lower frequencies to pass through. The precise cutoff frequency is determined by external components connected to the FB (feedback) pin.
