NOTE
1.
The closed gain should be 6dB or higher to prevent the oscillation. Unity gain follower application may cause the
oscillation.
2.
Minimize the load capacitor for the better performance. A large load capacitor CL reduces the frequency response and
causes oscillation or ringing.
3. Be careful to the circuit of high impedance. Input bias current influences an input noise and output offset voltage.
