MAX263BCPI

Overview

The MAX263BCPI is a pin-programmable universal switched-capacitor active filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two second-order filter sections housed in a 28-pin PDIP package with a .600-inch body width. The device operates on dual power supplies ranging from ±2.37 V to ±6.3 V, typically utilizing ±5 V. It supports center frequencies up to 57 kHz and allows independent programming of Q factor and operating mode via external logic inputs.

Feature Summary

• Pin-programmable control over center frequency, Q factor, and filter operating modes without external components
• Dual second-order filter sections enabling complex filter configurations such as bandpass, lowpass, highpass, notch, and allpass
• Universal architecture supporting various filter functions through simple digital input programming

Applications

• Audio signal processing requiring precise frequency selection
• Instrumentation systems needing programmable filtering stages
• Communications equipment utilizing switched-capacitor techniques for signal conditioning

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package dimensions match the 28-pin PDIP outline provided in the documentation. Ensure supply voltage requirements align with system design constraints before integration.

Selection Notes

Select this component when designing circuits requiring flexible analog filtering without discrete passive components. Consider the maximum center frequency limit of 57 kHz and the requirement for an external clock source. Evaluate the PDIP package suitability for through-hole mounting processes compared to surface-mount alternatives.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of pin-programmable universal filters. These devices share similar internal architectures but differ in maximum center frequency capabilities and specific feature sets. The MAX263 variant specifically targets applications requiring center frequencies up to 57 kHz.

Replacement Considerations

Direct replacements within the same family include MAX263AEPI or MAX263BCWI depending on package preference. Verify that substitute parts maintain compatibility with existing PCB footprints and electrical specifications.
