The is a two independent general-purpose high-performance Switched Capacitor Filter with an external clock and two to four resistors, each filter block can realize various second-order and first-order filtering functions. Each block has three outputs. One output can be configured to perform an allpass, highpass or notch function. The other two outputs perform bandpass and lowpass functions. The center frequency of each filter stage is tuned by using an external clock or a combination of a clock and resistor ratio. Up to a fourth-order biquadratic function can be realized with one LMF100. This allows for the production of a very low-offset, high-frequency filter building block. The LMF100 is pin-compatible with the industry standard MF10, but provides greatly improved performance.
