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.
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.
