MAX268AEWG+

Overview

The MAX268AEWG+ is a pin-programmable universal and bandpass filter IC manufactured by Analog Devices Inc./Maxim Integrated. It features two second-order filters housed in a 24-SOIC package with a width of 7.50mm. The device operates on a supply voltage ranging from 4.74V to 12.6V, or ±2.37V to ±6.3V. Its center frequency is specified at 140kHz. This component is designed for active filtering applications requiring programmable bandwidth and center frequency control via external pins.

Feature Summary

• Pin-programmable architecture allows configuration of filter characteristics without external microprocessor intervention.
• Integrates two independent second-order universal filters within a single integrated circuit.
• Supports both universal and bandpass filter configurations through external component selection.

Applications

• Signal processing circuits requiring precise bandpass filtering
• Audio frequency analysis systems
• Instrumentation front-end conditioning

Procurement Notes

Verify the specific suffix 'EWG+' against the manufacturer's current datasheet to confirm package dimensions and lead finish specifications. Ensure the operating supply voltage range aligns with system requirements before integration. Check for any product discontinuance notices or alternative recommendations from Analog Devices.

Selection Notes

Select this component when a dual second-order filter solution is required in a surface-mount package. Confirm that the 140kHz center frequency meets application needs. Evaluate the 24-SOIC footprint availability against PCB layout constraints. Compare power consumption and supply voltage tolerance with other available filter ICs.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of pin-programmable filters. These devices share similar internal architectures but differ in pin counts and package options. The MAX268 specifically offers two filters in a 24-pin format, distinguishing it from single-filter variants in the same series.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the MAX26x family. Verify if MAX263, MAX264, or MAX267 variants meet the specific filter count and package requirements. Cross-reference with Analog Devices' recommended replacement lists for discontinued components.
