MAX264BCWI+

Overview

The MAX264BCWI+ is a pin-programmable universal switched-capacitor filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on dual power supplies ranging from ±2.37V to ±6.3V and functions within an industrial temperature range of -40°C to +85°C. The device features two independent second-order sections housed in a 28-pin SOIC Wide package with a .300-inch body width. It supports center frequencies up to 140kHz, allowing for precise configuration of low-pass, high-pass, bandpass, band-reject, and all-pass responses through dedicated programming pins.

Feature Summary

• Supports five distinct filter response modes including low-pass, high-pass, bandpass, band-reject, and all-pass configurations via mode selection pins.
• Features independent programmability for center frequency and quality factor (Q) using dedicated digital input pins.
• Integrates two fully matched second-order switched-capacitor filter sections within a single monolithic IC.

Applications

• Signal conditioning circuits requiring adjustable bandwidth filtering
• Communication systems utilizing switched-capacitor techniques
• Instrumentation requiring precise analog signal processing

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the ordering suffix corresponds to the required temperature grade and packaging format. Ensure compatibility with existing board layouts regarding the 28-pin SOIC Wide footprint dimensions.

Selection Notes

Select this component when designing circuits requiring flexible analog filtering without external passive components. Evaluate the maximum operating frequency against the available clock rate. Verify that the supply voltage requirements align with the system's power rails before integration into the design.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of universal filters. These devices share common internal architectures but differ in specific performance characteristics and factory presets. The MAX264 variant specifically offers higher maximum center frequencies compared to other members of the series.

Replacement Considerations

Direct substitutes include MAX264ACWI+, MAX264BCPI+, and MAX264BCWE+. Verify package type and temperature range compatibility when selecting alternatives.
