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 applica-
tions. Thanks to the DMOS output stage the
TDA7563 has a very low distortion allowing a clear
powerful sound. Among the features, its superior
efficiency performance coming from the internal ex-
clusive structure, makes it the most suitable 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 conven-
tional class AB solutions.This device is equipped
with a full diagnostics array that communicates the
status of each speaker through the I²C bus.
