MF10CCWMX

Overview

The MF10CCWMX is a universal monolithic dual switched capacitor filter manufactured by Texas Instruments. It integrates two independent filter circuits within a single SOIC-20 package, designed for surface-mount installation. The device operates with a maximum supply voltage of 7 V and supports a cutoff frequency up to 30 kHz. It functions across four channels and is rated for an operating temperature range from 0°C to +70°C. The component requires external clocking to define its filter characteristics and includes provisions for gain adjustment and frequency tuning via external resistors.

Feature Summary

• Dual independent filter sections integrated on a single monolithic chip
• Universal configuration capability allowing implementation of low-pass, high-pass, band-pass, or notch responses
• Switched-capacitor architecture eliminates the need for precision external capacitors
• Frequency response determined by an external clock signal

Applications

• Audio signal processing and equalization circuits
• Instrumentation systems requiring precise frequency selection
• Data acquisition front-end filtering
• Telecommunications channel selection

Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance when sourcing. Confirm the SOIC-20 package dimensions match the PCB footprint requirements. Ensure the external clock source meets the frequency stability specifications required for the target cutoff frequency. Check moisture sensitivity levels for proper storage and reflow soldering profiles.

Selection Notes

Select this component when dual-channel filtering is required in a compact form factor. The switched-capacitor design simplifies layout by removing large passive components. Verify that the available external clock frequency allows for the desired cutoff frequency setting. Consider the 7 V maximum supply voltage limit against the system power rails.

Part Context

This part belongs to the MF10 series of universal filters. It is a successor to earlier discrete filter designs, offering improved accuracy and reduced board space. The MF10 family is widely used in applications where stable, programmable filtering is needed without the drift associated with RC active filters.

Replacement Considerations

The MAX7490 is a documented equivalent from Maxim Integrated offering similar dual switched-capacity functionality. The LTC1059 provides comparable performance in high-performance applications. Verify pin compatibility and external component requirements before substitution.
