Filter Building Blocks

Analog Devices offers an extensive line of continuous time and clock tunable (switched capacitor) filter building blocks. These devices were designed to simplify the implementation of band-pass, high-pass, low-pass, notch, or all-pass filters using classical filter realizations (such as Butterworth, Cauer, Bessel, and Chebyshev).
