LME49870 Datasheet, PDF (22/34 Pages) National Semiconductor (TI) – 44V Single High Performance, High Fidelity Audio Operational Amplifier

The LME49870 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.
Capacitive loads greater than 100pF must be isolated from
the output. The most straightforward 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.
Complete shielding is required to prevent induced pick up from external sources. Always check with oscilloscope for power line noise.
