Product Summary
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 of the TDA7565 under average listening condition is aligned to the conventional solutions (4 * 40 W).
