DESCRIPTION

The TDA7372B is a new technology class AB quad

channels Audio Power Amplifier in Multiwatt15

package designed for car radio applications.

Thanks to the fully complementary PNP/NPN out-

put configuration the TDA7372B delivers a rail to

rail voltage swing with no need of boostrap capacitors.

This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
