The 336 Hz cutoff frequency targets low-frequency signal chains.
A 4th-order filter gives steep roll-off — enough to reject harmonics above the passband without needing a multi-stage discrete design. The band-pass and low-pass modes let you configure it either as a tuned band-select filter or a low-pass anti-aliasing stage ahead of an ADC.
The MAX22707AUB+ comes in a 10-pin uMAX/uSOP package. The pinout is defined in the datasheet; key pins include supply, ground, filter input, and zero-crossing output.
As a complete 4th-order filter and zero-crossing detector, the MAX22707AUB+ integrates the filter network on-chip. External components are limited to supply decoupling and possibly input coupling capacitors depending on the signal source — refer to the datasheet for the recommended application circuit.
Typical applications include zero-crossing detection for AC power control (phase-angle firing, TRIAC triggering), low-frequency signal conditioning for tachometers or vibration sensors, and anti-aliasing filtering ahead of a slow ADC.
