* Independent a, frequency and gain adjustment
* Very low sensitivity to external component variation
* Separate low pass, high pass 'and band pass outputs
.
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 si.
