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.
