WebAug 6, 2024 · This topology is a two-pole (i.e. 12dB/octave) differential-in / single-ended out active low-pass filter. C1, C2, C3 and C4 plus R1, R2, R3, R4 and R6 determine the -3dB frequency. C5 AC couples R6, because the outputs of the CS4272 are DC biased at about 1/2 Vcc. These outputs can't drive significant DC current - thus a big coupling cap in C5.
