NJM2726
ULTRA HIGH SPEED SINGLE OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJM2726 is a high speed voltage feedback amplifier.
It provides a very high slew rate at 500V/µs. On a single 5V
supply the output swings from 0.3V to 3.8V with a 500Ω load
connect to 2.5V reference.
It is suitable for high speed differential signal processing.

■ Note:
Non-inverting amplifier
1.Unity gain follower application may cause the oscillation.
Recommended the total load capacitance is less than 3pF.
2.When the closed gain is lower than 20dB, place a compensation capacitor (CF: recommended from 1pF to 5pF), in
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, place a compensation capacitor (CF; recommended more than 1pF), in
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 2k-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 10pF.
The oscillation margin may be affected by the total load capacitance.
