The Butterworth response gives maximally flat passband gain — no ripple to amplify noise before the roll-off, which matters when you are placing this ahead of a SAR ADC or after a DAC reconstruction stage. ## Supply rails and signal swing It runs from a single 4.75 V to 11 V supply, or split ±2.375 V to ±5.5 V. The dual-rail option lets the input and output swing around ground without a DC-bias network — useful when the upstream sensor or downstream ADC is already bipolar. The single filter channel means one 8-SOIC per signal path; budget one package per channel in your BOM.","metaTitle":"MAX291ESA+T Analog Devices 8th-Order Butterworth Low-Pass","metaDescription":"MAX291ESA+T 8th-order Butterworth low-pass switched-capacitor filter from Analog Devices. 25 kHz cutoff, 8-SOIC, ROHS3, active production.
