DESCRIPTION The 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 alligned to the conventional solutions (4x40W).
