MF5CWM Datasheet PDF

National Semiconductor MF5CWM

The MF5 consists of an extremely easy to use general purpose CMOS active filter building block and an uncommitted op amp The filter building block together with an external clock and a few resistors can produce various second order functions The filter building block has 3 output pins One of the output pins can be configured to perform highpass allpass or notch functions and the remaining 2 output pins perform bandpass and lowpass functions The center frequency of the filter can be directly dependent on the clock frequency or it can depend on both clock frequency and external resistor ratios...
