MULTIPOWER BCD TECHNOLOGY MOSFET OUTPUT POWER STAGE

FLEXIWATT27

ORDERING NUMBER: TDA7563

DESCRIPTION

The TDA7563 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 TDA7563 has a very low distortion allowing a clear powerful sound. Among the features, its superior efficienc y perform ance com ing from the i nternal ex clusive structure, makes it the m os t s ui t abl e device to simplify the thermal management in high power sets.The dissipated output power under average listening condition is in fact reduced up to 50% when compared to the level provided by conventional class AB solutions.This device is equipped with a full diagnostics array that communicates the status of each speaker through the I
