MF10CCN

Active Filters Overview

The MF10CCN is a universal monolithic dual switched capacitor filter from the MF10-N series, manufactured by Texas Instruments. It integrates two independent second-order active filter building blocks in a 20-pin PDIP package. The device supports lowpass, bandpass, highpass, notch, and allpass configurations using external resistors and a clock signal. Operating ratings specify a supply voltage range of 9 V to 14 V and an operating temperature range of 0°C to 70°C. Electrical characteristics include a center frequency range up to 30 kHz, a clock frequency range of 5 Hz to 1 MHz, and a maximum supply current of 12 mA.

Active Filters Feature Summary

• Dual independent second-order filter sections capable of realizing various classical filter responses such as Butterworth, Bessel, Cauer, and Chebyshev.
• Flexible output configuration providing simultaneous lowpass, bandpass, and notch/allpass/highpass signals for each section.
• Center frequency stability directly dependent on external clock quality with adjustable clock-to-center-frequency ratios.

Active Filters Applications

• Cascading multiple units to construct higher-order filter functions like fourth-order Chebyshev low-pass filters.
• Signal conditioning stages requiring precise frequency selection via external clock oscillators.
• General-purpose analog filtering where component tolerance sensitivity must be minimized.

Active Filters Procurement Notes

Verify the specific suffix 'CCN' against the manufacturer's current product folder to confirm availability status. Ensure that the required operating temperature range aligns with the commercial grade specifications defined in the datasheet. Cross-reference pin assignments with the official SNOS547C document to prevent integration errors during PCB layout.

Active Filters Selection Notes

Select this component when a dual-channel state-variable filter topology is required within a single package. Consider the external resistor count and clock source requirements during the design phase. Evaluate the power supply constraints, as the device operates optimally with split supplies or a regulated single supply with mid-point biasing for analog ground reference.

Active Filters Part Context

The MF10CCN belongs to the MF10-N family of universal monolithic dual switched capacitor filters. This series provides general-purpose CMOS active filter building blocks designed for ease of use. The device allows for the synthesis of complex filter responses by cascading its internal second-order sections or connecting multiple packages together.

Active Filters Replacement Considerations

The LMF100 is identified in the datasheet as a pin-compatible device offering improved performance. Designers should consult the LMF100 datasheet if enhanced specifications are required while maintaining the same footprint.
