MAX294CWE+T

Overview

The MAX294CWE+T is an active filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as an 8th-order, lowpass, elliptic switched-capacitor filter with a cutoff frequency of 25 kHz. The component is housed in a 16-SOIC package and operates within a supply voltage range of 4.5 V to 5.5 V. It supports surface mount installation and is designed for applications requiring precise signal filtering characteristics.

Feature Summary

• Provides 8th-order lowpass elliptic filtering response
• Utilizes switched-capacitor technology for signal processing
• Features a fixed 25 kHz cutoff frequency

Applications

• Signal conditioning circuits requiring high-order attenuation
• Data acquisition systems needing anti-aliasing filters
• Audio processing equipment utilizing switched-capacitor architectures

Procurement Notes

Verify current availability status through authorized distributors, as this component may be subject to discontinuation or limited supply constraints. Confirm RoHS compliance and package integrity upon receipt. Cross-reference the manufacturer's official documentation for any recent design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when an 8th-order elliptic response is required at a specific 25 kHz frequency point. Ensure the system power supply remains stable between 4.5 V and 5.5 V to maintain filter accuracy. Consider the 16-SOIC footprint during PCB layout and verify that the switched-capacitor nature aligns with the application's clocking requirements.

Part Context

This part belongs to the MAX290-MAX299 series of active filters from Maxim Integrated. These components are designed to replace traditional passive LC filters, offering smaller size and easier integration into mixed-signal systems. The MAX294 specifically targets applications demanding steep roll-off characteristics without the complexity of discrete component tuning.
