It delivers a sharp roll-off characteristic typical of elliptic (Cauer) filters, with a cutoff frequency set at 50 kHz by the internal clock. The single filter channel operates from a 4.75 V to 11 V single supply or a split ±2.375 V to ±5.5 V rail, suiting it for both single-supply analog chains and bipolar signal conditioning. This part is aimed at anti-aliasing and reconstruction filtering in data-acquisition paths, as well as tone-decoding and frequency-selective stages where a steep transition band is needed. The 50 kHz cutoff places it at the boundary between audio-band and low-ultrasonic applications — think ultrasonic ranging receivers, vibration analysis front-ends, or high-speed modem channel filters. ## Active lifecycle, RoHS non-compliant — plan your assembly line The trade-off is RoHS non-compliance, which means the leads are tin-lead (SnPb) plated. ## Sourcing and supply posture As an active Maxim (now Analog Devices) part, the MAX297EPA is available through the independent distribution channel.","metaTitle":"MAX297EPA 8th-Order Elliptic Low-Pass Switched-Capacitor","metaDescription":"MAX297EPA 8th-order elliptic low-pass switched-capacitor filter in 8-DIP. 50 kHz cutoff, 4.75–11 V supply.

For a surface-mount footprint, the MAX297ESA+ in 8-SOIC is the functional equivalent. Both share the same 8th-order elliptic topology and 50 kHz cutoff."},{"question":"What are the alternatives with different cutoff frequencies?","answer":"The MAX297 is part of a family of pin-compatible 8th-order elliptic filters. The MAX296 has a cutoff of 25 kHz, and the MAX295 offers 12.5 kHz. All share the same 8-DIP or 8-SOIC footprint and supply range, so swapping to a different cutoff is a direct drop-in replacement."},{"question":"What is the typical application for MAX297EPA?","answer":"Typical uses include anti-aliasing filtering in data-acquisition systems, reconstruction filtering after DACs, tone decoding, and frequency-selective signal conditioning in instrumentation and communication equipment. The 50 kHz cutoff suits it for ultrasonic sensing, vibration analysis, and modem channel filters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX297EPA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX297EPA when reusing this data.
