MAX263AEPI

Overview

The MAX263AEPI is a pin-programmable universal switched-capacitor filter IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent second-order filters housed in a 28-pin plastic dual in-line package (PDIP) with a 0.600-inch width. The device operates on a nominal ±5V supply voltage and supports a center frequency range from 0.0004 kHz to 57 kHz. Designed for through-hole mounting, it provides flexible filtering capabilities including low-pass, high-pass, bandpass, and notch configurations via external pin connections.

Feature Summary

• Pin-programmable architecture allows configuration of filter type and cutoff frequency without external resistors or capacitors
• Dual-channel design integrates two independent second-order switched-capacitor filters within a single package
• Universal functionality supports multiple filter responses including low-pass, high-pass, bandpass, and notch modes

Applications

• Audio signal processing requiring precise frequency selection
• Instrumentation systems needing programmable analog filtering
• Communication equipment utilizing switched-capacitor techniques

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'EPI' corresponds to the PDIP-28 package variant. Check current lifecycle status as older Maxim products may face discontinuation. Ensure environmental compliance requirements match project specifications before procurement.

Selection Notes

Select this component when a dual-channel, pin-programmable switched-capacitor solution is required. Verify that the maximum center frequency of 57 kHz meets system bandwidth needs. Ensure the PCB layout accommodates the 28-pin DIP footprint. Consider thermal dissipation characteristics if operating near the upper temperature limits specified in the datasheet.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of universal switched-capacitor filters. These devices share similar internal architectures but differ in maximum center frequencies and package options. The MAX263 specifically targets applications requiring lower frequency ranges compared to its higher-frequency siblings in the series.

Replacement Considerations

Direct substitutes include other members of the MAX263/MAX264/MAX267/MAX268 family, provided the center frequency requirements align. Verify pin compatibility and package dimensions before substitution. Consult the official datasheet for detailed electrical parameter comparisons between variants.
