MAX263BEWI+

Overview

The MAX263BEWI+ is a pin-programmable universal active filter from the MAX263B series, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply with a voltage range of 2.37V to 6.3V. The device features a cutoff frequency of 57kHz and supports bandpass filtering configurations within a single channel. Designed for surface-mount applications, it is housed in a SO-Wide-28 package. The component functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Pin-programmable architecture allows configuration of filter parameters without external components.
• Supports universal and bandpass filter topologies for versatile signal processing.
• Integrated CMOS design eliminates the need for external capacitors or resistors.

Applications

• Telecommunications signal conditioning
• Instrumentation front-end filtering
• Audio processing circuits

Procurement Notes

Verify the specific suffix BEWI against official datasheets to confirm package type and temperature grade. Confirm availability status as distribution channels may list limited stock or discontinuation notices. Ensure compliance with RoHS directives if required for the target assembly process.

Selection Notes

Select this component when a single-channel, pin-programmable universal filter is required at frequencies up to 57kHz. Compare against the MAX263A series for dual-channel options or different voltage ranges. Verify that the SO-Wide-28 package fits the PCB footprint constraints.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of switched-capacitor filters. These devices allow microprocessor control over center frequency, Q, and filter mode via digital inputs. The MAX263 variant specifically offers single-channel operation optimized for general-purpose filtering tasks.
