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.

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.
