The elliptic topology gives a sharp transition band — the stopband attenuation rises quickly after cutoff — which means you can separate a 10 kHz passband from out-of-band noise with a narrower guard band than a Butterworth or Bessel of the same order would allow. That matters when the next stage is an ADC that folds high-frequency noise back into the baseband. No extra regulator, no bipolar supply — just the logic rail and a clock source. The 10 kHz cutoff sets the anti-aliasing boundary. If your ADC samples at 20 kHz or higher, the filter attenuates signals above 10 kHz so they do not alias into the passband. The 8th-order elliptic response means the stopband attenuation starts within a few hundred Hz of cutoff — much steeper than a 4th-order Butterworth, which would need a higher cutoff to achieve the same alias rejection and would let more out-of-band noise through. Because the filter is switched-capacitor, the cutoff tracks the clock frequency. The datasheet clock-to-cutoff ratio is fixed — a 100 kHz clock gives a 10 kHz cutoff. That lets you tune the filter by changing the clock, but it also means the clock noise couples into the signal path if the clock is not clean. ## Active production — no forced redesign That means standard lead times apply, and the part will be available for new designs without a looming end-of-life notice. The part is supplied in Tube and is ROHS3 compliant. The 8-SOIC package is a common footprint — 1.27 mm pitch, 3.90 mm body width — so it fits existing land patterns without a board spin.","metaTitle":"MAX7407CSA+ 8th-Order Elliptic Low-Pass Filter, 10 kHz","metaDescription":"Active production — Analog Devices MAX7407CSA+ 8th-order elliptic switched-capacitor low-pass filter, 10 kHz cutoff, 2.7 V to 3.6 V supply, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Package":"Tube","Filter Type":"Elliptic, Low Pass Switched Capacitor","Filter Order":"8th","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 3.6V","Number of Filters":"1","Supplier Device Package":"8-SOIC","Frequency - Cutoff or Center":"10kHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.17","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.17000","currency":"USD"},{"qty":10,"price":"$9.18500","currency":"USD"},{"qty":25,"price":"$8.75840","currency":"USD"},{"qty":100,"price":"$7.60470","currency":"USD"},{"qty":250,"price":"$7.26292","currency":"USD"},{"qty":500,"price":"$6.62206","currency":"USD"},{"qty":1000,"price":"$5.76760","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX7400-MAX7407.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the cutoff frequency of the MAX7407CSA+?","answer":"The cutoff frequency is 10 kHz.
