4th-Order Elliptic Notch Filter

General Description\nThe LMF90 is a fourth-order elliptic notch (band-reject) filter based on switched-capacitor techniques. No external components are needed to define the response function. The depth of the notch is set using a two-level logic input, and the width is programmed using a three-level ■ Center frequency set by external clock or on-board clock oscillator\n■ No external components needed to set response char acteristics\n■ Notch width, attenuation, and clock-to-center-frequency ratio independently programmable\n■ 14 pin 0.3× wide packageApplications\n■ Automatic test equipment\n■ C;
