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.

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.
