MF10CN+

Overview

The MF10CN+ is a dual universal switched-capacitor filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features two independent fourth-order filters, each capable of providing low-pass, high-pass, band-pass, or notch responses. The component operates with a cutoff frequency centered at 30 kHz and supports a supply voltage range from 2.6 V to 5.5 V. It utilizes a 20-pin DIP package for through-hole mounting.

Feature Summary

• Dual independent fourth-order switched-capacitor filter sections
• Configurable as low-pass, high-pass, band-pass, or notch filters
• Universal design allowing flexible signal processing applications

Applications

• Audio signal processing and equalization
• Instrumentation and measurement systems
• Telecommunications filtering

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or surplus channels. Ensure compatibility with existing PCB footprints and soldering processes. Check for alternative lead times and potential supply chain constraints associated with discontinued parts.

Selection Notes

Select this component when dual fourth-order filtering is required in a single package. Consider the 30 kHz cutoff frequency suitability for audio or intermediate frequency applications. Evaluate the DIP package constraint against available board space and assembly methods compared to surface-mount alternatives.

Part Context

This part belongs to the MF10 family of analog filters. It provides a compact solution for implementing complex filter responses without external passive components. The device integrates clock generation capabilities internally, simplifying the surrounding circuit design compared to discrete implementations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may require redesigning the application circuit or selecting compatible modern equivalents from the manufacturer's current portfolio.
