AF161 Datasheet | National Semiconductor

Description The AF161 consists of 2 general purpose state variable active filters in a single package. By using only 4 external resistors for each section, various second order functions may be formed. Low pass, high pass, and band pass functions are avaiable simultaneously at separate outputs. In addition, there are 2 unmitted operational amplifiers which are available for buffering or for forming all pass and notch functions. Any of the classical filter configurations, such as Butterworth, Bessel, Cauer, and Chebyshev can be easily formed. The AF161 is pin - patible with the AF151. BIFET is a trademark of National Semiconductor Corporation Features - Independent a, frequency and gain adjustment - Very low sensitivity to external ponent variation - Separate low pass, high pass 'and band pass outputs - Operation to 40 k Hz - a range to 500 - Wide power supply...
