MAX263BEPI

Overview

The MAX263BEPI is a pin-programmable universal and bandwidth active filter manufactured by Analog Devices Inc./Maxim Integrated. It utilizes switched-capacitor technology to provide precise filter functions without external components. The device operates on a single +5V supply voltage with a maximum rating of 12.6V and minimum of 4.74V. It features two independent second-order filter sections housed in a 28-pin PDIP package. The center frequency range extends from 0.0004 kHz to 57 kHz, determined by an input clock and 6-bit program inputs.

Feature Summary

• Pin-programmable architecture allows configuration of center frequency, Q factor, and filter operating mode via digital inputs.
• Contains two independent second-order filter sections capable of bandpass, lowpass, highpass, notch, and allpass configurations.
• Operates on a single +5V power supply, simplifying system design compared to dual-supply alternatives.

Applications

• Audio signal processing requiring programmable filtering characteristics
• Instrumentation systems needing precise analog signal conditioning
• Communication equipment utilizing switched-capacitor filter stages

Procurement Notes

Verify the specific suffix 'BEPI' against official manufacturer documentation to confirm the exact temperature grade and packaging variant. Ensure compatibility with existing PCB footprints for the 28-pin PDIP format. Confirm availability status through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component when a single-supply, pin-programmable switched-capacitor filter is required. Compare the 57 kHz maximum center frequency against application needs. Verify that the 28-pin PDIP package fits the mechanical constraints. Consider the MAX263AEPI if extended industrial temperature ranges are necessary.

Part Context

The MAX263 belongs to a family of universal active filters including the MAX264, MAX267, and MAX268. These devices share similar functional architectures but differ in center frequency ranges and package options. The MAX263 specifically targets applications requiring frequencies up to 57 kHz.

Replacement Considerations

The MAX263AEPI serves as a direct replacement offering identical functionality within an extended temperature range. Verify package compatibility and electrical specifications before substitution.
