L2720D
DESCRIPTION
The L2720D is a monolithic integrated circuits in SO16 package, intended for use as power operational
amplifiers in a wide range of appli cations including
servo amplifiers and power supplies.
It is particularly indicated for driving, inductive loads,
as motor and finds applications in compact-disc VCR
automotive, etc.
The high gain and high output power capability provide superior performance whatever an operational
amplifier/power booster combination is required.
