MF100CCM

Overview

The MF100CCM is a universal monolithic dual switched-capacitor filter manufactured by Texas Instruments. It integrates two independent second-order filter sections within a single package, enabling the implementation of complex higher-order filtering responses through cascading. The device operates with an external clock and supports low-pass, high-pass, band-pass, and band-stop configurations. It features a cutoff or center frequency determined by the ratio of the clock frequency to the internal circuitry, offering precise tuning capabilities without requiring external passive components for frequency setting.

Feature Summary

• Integrates two independent second-order filter sections on a single chip
• Supports versatile filter functions including low-pass, high-pass, band-pass, and band-stop
• Utilizes switched-capacitor technology for precise frequency control via external clock
• Eliminates need for external resistors and capacitors in frequency-determining networks

Applications

• Audio signal processing and equalization circuits
• Instrumentation and measurement system filtering
• Telecommunications channel selection and demodulation
• Data acquisition systems requiring anti-aliasing filters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance and lead time constraints as production may be discontinued. Request detailed datasheets and application notes from Texas Instruments to ensure compatibility with existing designs. Validate substitute part numbers such as LTC1060CSW#PBF against original specifications before procurement.

Selection Notes

Evaluate clock frequency requirements relative to desired cutoff frequencies when selecting this component. Consider package type and pinout compatibility during PCB layout design. Assess power supply voltage ranges and operating temperature limits against environmental conditions. Review switching noise implications in sensitive analog circuits and implement appropriate grounding strategies.

Part Context

The MF100CCM belongs to the MF10 family of universal switched-capacitor filters developed by Texas Instruments. This series provides flexible analog filtering solutions using integrated switched-capacitor techniques. The component represents a transition toward fully integrated active filter implementations, reducing reliance on discrete passive components while maintaining performance accuracy in various electronic applications.

Replacement Considerations

LTC1060CSW#PBF by Analog Devices Inc. serves as a documented similar replacement option.
