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-ohm 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-ohm) 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. non-inverting amplifier DUT RF CL RL CL RL CF RG inverting amplifier CF RF RG DUT -3- NJM2712 ■ TYPICAL CHARACTERISTICS Operating
