MOSFET OUTPUT POWER STAGE
FLEXIWATT27
ORDERING NUMBER: TDA7565
DESCRIPTION
The TDA7565 is a new BCD technology QUAD
BRIDGE type of car radio amplifier in Flexiwatt27
package specially intended for car radio applica-
tions. 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 compo-
nents.The dissipated power under average listen-
ing condition is alligned to the conventional
solutions (4x40W).
