MAX267AEWG+

Overview

The MAX267AEWG+ is a pin-programmable universal and bandwidth filter manufactured by Analog Devices Inc./Maxim Integrated. It utilizes switched-capacitor technology to provide flexible filtering capabilities in a single integrated circuit. The device operates on a single 5V supply voltage and is housed in a 24-pin SOIC wide package designed for surface-mount installation. Key electrical specifications include a cutoff frequency of 57 kHz, a maximum power supply voltage of 12.6 V, and a minimum operating voltage of 4.74 V. It supports two channels and functions within an industrial temperature range from -40°C to +85°C.

Feature Summary

• Pin-programmable configuration allows selection of center frequency, Q factor, and operational modes without external components.
• Switched-capacitor architecture enables precise tuning and stability independent of external passive component tolerances.
• Universal filter topology supports multiple filter responses including low-pass, high-pass, bandpass, and notch configurations.

Applications

• Military communication systems requiring signal conditioning
• Industrial control instrumentation
• Test equipment signal processing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific revision. Check for obsolescence notices as the product lifecycle indicates discontinuation. Ensure packaging integrity upon receipt to prevent damage to the SOIC-24 leads.

Selection Notes

Select this component when pin-programmable flexibility is required over fixed-response filters. Verify that the 57 kHz cutoff frequency aligns with system bandwidth requirements. Ensure the design accommodates the SOIC-24 footprint and thermal characteristics. Consider the single-supply operation constraints relative to the application's voltage rails.

Part Context

This part belongs to the MAX267A series of active filters. It shares architectural similarities with the MAX263, MAX264, and MAX268 families but offers specific programmability features tailored for universal filtering applications. The device represents Maxim Integrated's approach to simplifying analog filter design through integration.

Replacement Considerations

Consult official datasheets for cross-reference information. No public substitute part numbers are confirmed in the provided documentation. Evaluate functional equivalence regarding pin compatibility and electrical parameters if sourcing alternatives.
