DESCRIPTION
The L2750 is a new technology class AB dual
power operational amplifier assembled in Multi-
watt 11 package.
Thanks to the fully complementary PNP/NPN out-
put configuration the L2750 can deliver a rail-to-

Multiwatt-11
ORDERING NUMBER: L2750
rail output voltage swing even at the highest cur-
rent.
Additional feature is the very low current Stand-
By function.
The high application flexibility of the L2750 makes
the device suitable for either motor driving/control
and audio applications purposes.
