MAX263BCWI+

Overview

The MAX263BCWI+ is a single-channel, pin-programmable universal and bandpass active filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.37V to 6.3V and supports a center frequency of 57kHz. The device is housed in a 28-pin SOIC-Wide (SO-wide-28) surface-mount package. It functions across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Pin-programmable architecture allows configuration for various filter responses without external component changes.
• Universal topology supports multiple filter types including low-pass, high-pass, bandpass, and notch configurations.

Applications

• Telecommunications signal processing
• Instrumentation front-end filtering
• Audio equipment frequency selection

Procurement Notes

Verify the specific suffix 'BCWI+' against official documentation to confirm the exact grade and package variant. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the ordering information matches the manufacturer's current product lifecycle notifications before finalizing procurement plans.

Selection Notes

Select this component when a single-channel, pin-programmable solution is required for frequencies around 57kHz. Verify that the 2.37V to 6.3V supply range aligns with system power constraints. Ensure the SO-wide-28 package footprint fits the PCB layout requirements compared to other MAX263 variants like the PDIP or standard SOIC packages.

Part Context

The MAX263BCWI+ belongs to the MAX263/MAX264/MAX267/MAX268 family of pin-programmable universal filters. This series utilizes switched-capacitor technology to provide flexible filtering solutions. The BCWI+ designation indicates a specific commercial grade and wide-body SOIC package variation within this broader product line.

Replacement Considerations

Direct replacements include other MAX263 variants such as MAX263ACWI+ or MAX263AEPI+, provided the channel count and package type match the design requirements. Verify electrical specifications and operating temperature ranges when substituting between different suffix grades.
