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).
