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.

Capacitive loads greater than 100pF must be isolated from
the output. The most straight forward way to do this is to put
a resistor in series with the output. This resistor will also pre-
vent excess power dissipation if the output is accidentally
shorted.
