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. non-inverting amplifier DUT RF CL RL CL RL CF RG inverting amplifier CF RF RG DUT -3- NJM2712 ■ TYPICAL CHARACTERISTICS Operating Current vs. Ambient Temperature Operating Current vs.Operating Voltage 6 6 5 5 Operating Current [mA] Operating Current [mA] Vin=0V,Ta=25℃ 4 3 2 1 Vin=0V 4 V+/V-=±4.5V 3 V+/V-=±2.5V V+/V-=±2.0V 2 1 0 0 0±0 1±1 2 ±2 3 ±3 4 ±4 ±55 -50 0 Input Offset Voltage vs. Ambient Temperature + 800 600 0 -0.5 -1 -1.5 400 200 0 -200 -400 -600 -800 -50 0 50 100 -50 150 0 150 Vin=±300ｍV,RL=1kΩ,Ta=25°C 5 -
