Overview
The MF10CCWMX/NOPB, produced by Texas Instruments, is a Universal Monolithic Dual Switched Capacitor Filter. This device is part of the MF10-N series and is designed to be highly versatile and easy to use. It consists of two independent second-order filter sections, each capable of producing various filter functions such as lowpass, bandpass, highpass, notch, and allpass. The filter's center frequency is proportional to the clock frequency applied, making it highly adjustable and suitable for a wide range of applications.
