Application Information
APPLICATION HINTS
The LME49722 is a high speed operational amplifier which
can operate stably in most of the applications. For the appli-
cation with gain greater than 2, capacitive loads up to 100pF
will cause little change in the phase characteristics of the am-

plifiers and are therefore allowable. Capacitive loads greater
than 10pF must be isolated from the output, if the gain value
is less than 2. The most straightforward way to do this is to
put a resistor (its value
resistor will also prevent unnecessary power dissipation if the
output is accidentally shorted.
