What this filter does and where it fits
The Maxim MAX7410CUA+ is a 5th-order Butterworth low-pass switched-capacitor filter with a 15 kHz cutoff frequency. It operates from a single 4.5 V to 5.5 V supply and comes in an 8-uMAX/uSOP surface-mount package. The Butterworth response delivers a maximally flat passband — no ripple in the band of interest — making it a natural fit for anti-aliasing before an ADC or for smoothing the output of a DAC in audio or instrumentation chains where amplitude flatness matters more than a sharp roll-off.
15 kHz cutoff — what it decides on the BOM
The 15 kHz cutoff sets the usable bandwidth. For audio, that covers the full audible range with headroom; for sensor conditioning, it matches the bandwidth of many accelerometers and pressure sensors. If your signal chain needs a higher or lower corner, this part forces you to change the clock — the cutoff tracks the external clock frequency in a switched-capacitor filter. The single filter channel handles one signal path; multi-channel designs need one device per channel.
Supply and package constraints
The 4.5 V to 5.5 V supply range ties this filter to a regulated 5 V rail. The 8-uMAX/uSOP package (3.00 mm width) is a small outline — fine for dense PCBs, but the 0.118" body pitch means hand-soldering is tight. Tube delivery is standard; if your pick-and-place prefers tape, verify the reel option with your supplier.
Lifecycle and sourcing reality
The MAX7410CUA+ is listed as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect. No pin-compatible second source is recorded in the available cross-reference data, so dual-sourcing would require a different filter topology or package.
