The Butterworth response delivers maximally flat passband gain — no ripple up to the corner — making it a clean choice for anti-aliasing or reconstruction in audio-bandwidth data-acquisition paths where amplitude flatness matters more than a sharp roll-off. Switched-capacitor architecture means the cutoff is set by an internal clock, so no external RC network is needed. The 45 kHz corner suits applications like ADC pre-filtering for signals up to about 20 kHz, leaving margin for the filter's transition band before aliasing components fold in. ## Supply and package — board-fit constraints Supplied in tube packaging. The 8-pin MSOP/TSSOP-compatible land pattern is widely supported; no special thermal pad or exposed paddle to route.","metaTitle":"MAX7420CUA+ 5th-Order Butterworth Low-Pass Filter, 45kHz","metaDescription":"Active 5th-order Butterworth switched-capacitor low-pass filter from Analog Devices. 45kHz cutoff, 4.5V–5.5V supply, 8-uMAX/uSOP package.
