• -3db Bandwidth: 40MHz @ gain = 12dB on 25

Choosing the feedback circuit
30/37
The cutoff frequency is not gain-dependent and so becomes:
The damping factor is calculated by the following expression:
The higher the gain the more sensitive the damping factor is. When the gain is higher than
1, it is preferable to use some very stable resistor and capacitor values. In the case of
R1 = R2:
