Hello,
I need to implement a very selective 2280Hz notch filter in order to remove that component in an audio signal.
Is it possible to achieve it with the MF10-N
Any other alternative?
Many thanks

The datasheet gives a spec of f_o * Q <= 200kHz
So at f_o = 2280Hz, I suppose this suggests you could achieve a Q (the larger the Q the more selective your filter) of up to 87.
Perhaps this is selective enough for you? I graphed the 2nd order transfer function,
[s^2 + (Omega)^2 ]/(s^2 + (Omega)*s/Q + (Omega)^2)
with a Q of 87 and with an Omega = 2*Pi*2280 and got the following:
