Flexiwatt27
Description
The TDA7565 is a new BCD technology quad
bridge type of car radio amplifier in Flexiwatt27
package specially intended for car radio
applications. Thanks to the DMOS output stage
the TDA7565 has a very low distortion allowing a
clear powerful sound.
The built-in voltage converter control block
assures a very high output power with an
extremely low number of added components.
The dissipated power under average listening
condition is aligned to the conventional solutions
(4 x 40 W).
