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 ±2.37 V to ±6.3 V and functions within a commercial temperature range of 0°C to +70°C. The device utilizes a 28-pin SOIC-Wide (SOICW) surface-mount package with a .300-inch width. It supports center frequencies up to 140 kHz and features two independent second-order filter sections.

Feature Summary

• Pin-programmable configuration for center frequency and quality factor
• Supports multiple filter modes including low-pass, high-pass, band-pass, band-stop, and all-pass
• Dual independent second-order filter sections integrated on a single chip

Applications

• Signal processing systems requiring programmable filtering
• Communication equipment utilizing switched-capacitor techniques
• Audio signal conditioning circuits

Procurement Notes

Verify the specific suffix BCWI against official documentation to confirm the exact temperature grade and package variant. Ensure that the ordering information aligns with current manufacturer specifications, as component availability and detailed ordering codes may change over time without prior notice.

Selection Notes

Select this component when designing circuits requiring flexible filter topologies without external passive components. Confirm that the required clock frequency ratio and Q-factor programming pins are accessible in the system design. Verify that the supply voltage requirements match the available power rails in the target application environment.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of universal filters. These devices share common architectural features such as internal resistor and capacitor integration, eliminating the need for external RC networks. The MAX264 specifically offers higher maximum center frequencies compared to other members of the series.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the same product family. Verify compatibility regarding pin configurations and electrical characteristics before implementing any alternative components.
