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- 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. This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice. October 1991 BLOCK DIAGRAM Multiwatt-11 ORDERING NUMBER: L2750
