MAX294EPA+

Overview

The MAX294EPA+ is an active filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It implements an 8th-order elliptic low-pass switched-capacitor filter topology. The device operates with a cutoff frequency of 25 kHz and is housed in an 8-pin PDIP package. This component is designed for signal processing applications requiring high selectivity and precise frequency response characteristics within the specified operational range.

Feature Summary

• Implements an 8th-order elliptic low-pass filter response
• Utilizes switched-capacitor technology for frequency control
• Provides high selectivity suitable for precision signal conditioning

Applications

• Signal processing systems requiring steep roll-off characteristics
• Precision instrumentation where noise rejection is critical
• Data acquisition front-ends needing anti-aliasing filtering

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and pin compatibility before integration. Review latest manufacturer documentation for any design-in updates or lifecycle status changes. Ensure environmental compliance requirements match project specifications.

Selection Notes

Select this component when an 8th-order elliptic response is required without external passive components. Consider the 25 kHz cutoff frequency relative to the system clock rate. Evaluate the switched-capacitor nature against input signal bandwidth limitations. Compare performance against lower-order alternatives if complexity reduction is necessary.

Part Context

This part belongs to the Maxim Integrated active filter family, specifically focusing on switched-capacitor solutions. It complements other filter ICs by offering higher order responses in compact packages. The series supports various cutoff frequencies and filter types for diverse analog signal conditioning needs.
