MAX264BEPI

Overview

The MAX264BEPI is a pin-programmable universal switched-capacitor active filter manufactured by Analog Devices Inc./Maxim Integrated. It features two second-order filter sections housed in a 28-pin plastic dual in-line package (PDIP). The device supports center frequencies up to 140 kHz and operates on dual power supplies ranging from ±2.37 V to ±6.3 V. It allows independent programming of the center frequency and quality factor via external clock inputs and digital control pins.

Feature Summary

• Pin-programmable architecture enables precise configuration of filter functions without external components
• Dual second-order sections allow simultaneous implementation of multiple filter topologies
• Supports versatile configurations including bandpass, lowpass, highpass, notch, and allpass responses

Applications

• Signal processing systems requiring programmable filtering
• Instrumentation circuits needing adjustable bandwidth selection
• Communication equipment utilizing switched-capacitor filter stages

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes against current datasheet documentation before procurement. Ensure supply chain sources provide valid traceability records for this discontinued series component.

Selection Notes

Select this component when designing circuits requiring flexible analog filtering with minimal external parts. Evaluate the maximum center frequency capability against system signal requirements. Verify that the available PDIP-28 package fits within the mechanical constraints of the target enclosure design.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of universal active filters. These devices share common architectural features but differ in performance specifications such as maximum operating frequency and noise characteristics. The MAX264 variant specifically targets applications requiring higher cutoff frequencies compared to lower-speed siblings.

Replacement Considerations

Direct replacements include other members of the MAX26x family such as the MAX263, MAX267, or MAX268. Verify pin compatibility and electrical parameter alignment before substitution.
