■ Note:

non-inverting amplifier

1.The closed gain should be 6dB or higher to prevent the oscillation.

Unity gain follower application may cause the oscillation.

2.When the closed gain is lower than 20dB, use a compensation capacitor (CF: about 5pF),

parallel with the feedback resistor RF to avoid oscillation.

3.Recommended feedback resistor is less than 2k-ohom to keep the flatness of the frequency response.

4.Minimize the load capacitor for the better performance.

A large load capacitor CL reduces the frequency response and causes oscillation or ringing.

inverting amplifier

1.When the closed gain is lower than 20dB, use a compensation capacitor

(CF; recommended from 1pF to 5pF), parallel with the feedback resistor RF to avoid oscillation.

2.Minimize the feedback resistor to keep the frequency response and the slew rate.

(recommended about 1k-ohom)

The proper compensation capacitor CF can counteract oscillation even with a large feedback resistor RF.

3.Total load capacitance should be not more than 100pF.

The oscillation margin may be affected by the total load capacitance.
