MAX296EPA+

Overview

The MAX296EPA+ is an 8th-order, lowpass, switched-capacitor filter in the MAX291 series. It provides a Bessel response characterized by low overshoot and fast settling times. The device operates with a clock-to-corner frequency ratio of 50:1, allowing corner frequencies from 0.1Hz to 50kHz. It supports single +5V or dual ±5V supplies, features an internal oscillator or external clock input, and includes an uncommitted operational amplifier for additional filtering stages.

Feature Summary

• Bessel filter response optimized for preserving step input shapes and ensuring rapid settling
• Integrated uncommitted operational amplifier available for anti-aliasing or post-filtering applications
• Flexible clocking architecture supporting both internal oscillator generation and external digital signals

Applications

• Anti-aliasing filters preceding analog-to-digital converters
• Post-filtering stages following digital-to-analog converters
• Noise analysis systems requiring precise signal conditioning
• Line-noise filtering for 50Hz or 60Hz power line interference

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions remain within specified limits to maintain reliability. Validate pin configurations against the datasheet before integration into printed circuit board layouts.

Selection Notes

Select this model when a Bessel response is required for minimal phase distortion. Verify that the application requires a maximum corner frequency up to 50kHz. Ensure the design accommodates the necessary clock frequency range relative to the desired cutoff point. Confirm compatibility with single or dual supply voltage architectures.

Part Context

This component belongs to the MAX291 family of switched-capacitor filters manufactured by Analog Devices / Maxim Integrated. The 'E' suffix indicates an extended temperature range of -40°C to +85°C. The 'PA' designation specifies an 8-pin plastic DIP package suitable for through-hole mounting.

Replacement Considerations

The MAX291 serves as the Butterworth variant within the same family. The MAX295 offers a higher maximum corner frequency of 50kHz but maintains a Butterworth response. Cross-referencing specific filter characteristics is essential before substitution.
