Overview
The MF10CCN, produced by Texas Instruments, is a Universal Monolithic Dual Switched Capacitor Filter. This device is designed to be highly versatile and easy to use, serving as a general-purpose CMOS active filter. It consists of two independent filter building blocks, each capable of producing various second-order filter functions such as lowpass, highpass, allpass, and notch filters. The center frequency of the filter is proportional to the frequency of the square wave applied to the clock input, making it highly adjustable and accurate.
