DESCRIPTION

The TDA7563PD is a new BCD technology Quad

Bridge type of car radio amplifier in PowerSO36

package specially intended for car radio applica-

tions. Thanks to the DMOS output stage the

TDA7563PD has a very low distortion allowing a

clear powerful sound. Among the features, its su-

perior efficiency performance coming from the in-

ternal exclusive structure, makes it the most

suitable device to simplify the thermal manage-

ment 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
