    ... Application Hints The LME49710 is a high speed op amp with excellent phase margin and stability. Capacitive loads up to 100pF will cause little change in the phase characteristics of the amplifiers and are therefore allowable. Noise Measurement Circuit Complete shielding is required to prevent induced pick up from external sources. Always check with oscilloscope for power line noise. ...
