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 2kΩ 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- NJM2710 ■ TYPICAL CHARACTRERISTICS Supply Current vs. Ambient Temperature Supply Current vs. Supply Voltage VIN=No Signal,GV=6dB,RS=50Ω V+/V-=±2.5V,VIN=No Signal,GV=6dB RS=50Ω,RF=1kΩ,RG=1kΩ,RL=2kΩ 15 15 14 14 13 13 Supply Current [mA] Supply Current [mA] RF=1kΩ,RG=1kΩ,RL=2kΩ,Ta=+25oC 12 11 10 9 8 12 11 10 9 8 7 7 6 6 5 1.0 5 2.0 3.0 4.0 Supply Voltage ±V [V] 5.0 -50 Input Offset Voltage vs. Ambient Temperature 2 Input Bias Current [uA] Input Offset Voltage [mV] V+/V-=2.5V 1 0 -1 -2 1 0 -1 -2 -3 -3 -50 -25 0 25 50 75 Ambient Temperature [oC] -50 100 -25 0 25 50 75 Ambient Temperature [oC] 100 Common Mode Rejection Ratio vs. Ambient Temperature Input Offset Current vs. Ambient Temperature V+/V-=2.5V V+/V-=2.5V 500 70 Common Mode Rejection Ratio [dB] Input Offset Current [nA] 100 3 -4 450 400 350 65 60 55 50 45 40 300 -50 -4- 0 25 50 75 Ambient Temperature [oC] Input Bias Current vs. Ambient Temperature V+/V-=2.5V 2 -25 -25 0 25 50 75 Ambient Temperature [oC] 100 -50 -25 0 25 50 75 Ambient Temperature [oC] 100 NJM2710 ■ TYPICAL CHARACTRERISTICS V- Common Mode Rejection Ratio vs. Ambient Temperature V+ Common Mode Rejection Ratio vs. Ambient Temperature V+/V-=2.5V V Common Mode Rejection Ratio [dB] 120 110 100 90 80 70 60 120 110 100 90 80 70 60 -
