TDA7565 Intelligent high efficiency (class SB) quad BTL ouput with full I²C diagnostics, built in step up and mute input

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.

Furthermore, the converter makes the TDA7565 compliant to the most recent OEM specifications for low voltage operation (so called 'start-stop' battery profile during engine stop), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection.
