AF161 Datasheet - National Semiconductor

AF161 Dual Universal Active Filter

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, the.
