MAX296ESA

Overview

The MAX296ESA is an active, eighth-order lowpass switched-capacitor filter manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply with a specified range of 4.75V to 11V. The device features a cutoff frequency of 50 kHz and utilizes a single-channel architecture. Designed for surface-mount applications, it is housed in an SOIC-8 package. The component supports an operating temperature range from -40°C to +85°C. This integrated circuit provides high-performance filtering capabilities within a compact form factor suitable for various signal processing tasks.

Feature Summary

• Eighth-order lowpass filtering capability using switched-capacitor technology
• Single-channel operation optimized for 5V power supplies
• Surface-mount construction in an SOIC-8 package

Applications

• Signal conditioning circuits requiring steep roll-off characteristics
• Data acquisition systems utilizing switched-capacitor architectures
• Audio and instrumentation front-end filtering stages

Procurement Notes

Verify the specific suffix designation when sourcing components, as packaging variations such as tape-and-reel formats may exist within the product family. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies. Ensure that the selected variant matches the required mechanical footprint and thermal specifications for the target application environment.

Selection Notes

Select this component when an eighth-order response is necessary without cascading multiple discrete filter stages. Evaluate the requirement for external clocking, as switched-capacitor filters depend on a precise timing source relative to the cutoff frequency. Compare performance against higher-order alternatives if steeper attenuation is needed, or consider lower-order options for reduced complexity and cost in less demanding signal paths.

Part Context

The MAX296ESA belongs to the MAX295/MAX296 series of switched-capacitor filters. These devices are designed to replace bulky passive LC filters in modern electronic systems. The series offers programmable characteristics through external clock adjustments, providing flexibility in system design while maintaining a small physical profile and low power consumption typical of integrated analog solutions.

Replacement Considerations

The MAX296ESA+T serves as a direct replacement offering identical electrical specifications but supplied in a tape-and-reel format instead of tube packaging. Verify pin compatibility and functional equivalence before substituting other generic eighth-order lowpass filters.
