MF10CCWM

Active Filters Overview

The MF10CCWM is a universal monolithic dual switched capacitor filter from the MF10 series, housed in a 20-pin wide-body SOIC package. It contains two independent second-order building blocks capable of producing highpass, lowpass, bandpass, notch, and allpass functions using external resistors and a clock signal. The device operates on supply voltages up to 14V with a maximum center frequency of 30 kHz. Key electrical parameters include a typical gain-bandwidth product of 2.5 MHz, a slew rate of 7 V/µs, and a clock-to-center-frequency ratio accuracy of ±0.6% for the MF10C grade.

Active Filters Feature Summary

• Dual independent second-order state-variable filter sections
• Configurable outputs for lowpass, bandpass, highpass, notch, and allpass responses
• Center frequency stability directly dependent on external clock quality
• Low sensitivity to external component variation

Active Filters Applications

• Cascaded higher-order filter synthesis (e.g., Butterworth, Chebyshev)
• Universal active filter design requiring precise frequency control
• Signal processing stages needing multiple filter topologies per package

Active Filters Procurement Notes

Verify the specific suffix against the datasheet to confirm temperature range and performance grade. The CC suffix indicates commercial temperature operation. Ensure the ordering code matches the required package style and RoHS compliance status as listed in official Texas Instruments documentation before procurement.

Active Filters Selection Notes

Select this component when a dual-channel switched capacitor solution is required for frequencies up to 30 kHz. Consider the LMF100 for pin-compatible improved performance. Verify that the application can provide a stable clock source, as filter accuracy relies heavily on clock-to-center-frequency ratio precision.

Active Filters Part Context

The MF10CCWM belongs to the MF10-N family of universal monolithic dual switched capacitor filters. It shares the same internal architecture as other MF10 variants but differs in packaging and temperature specifications. The SOIC-20 package allows for surface-mount integration while maintaining the functional capabilities of the original PDIP version.

Active Filters Replacement Considerations

The LMF100 is identified in the datasheet as a pin-compatible device with improved performance. Verify compatibility regarding offset voltage and dynamic range if substituting.
