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 I

Each audio channel operates independently from each other. If any of the a.m. faults occurs, only the channel(s) interested is shut down. A check of the output status is made every 1 ms (fig ...

    ... I C BUS INTERFACE Data transmission from microprocessor to the TDA7563 and viceversa takes place through the 2 wires I face, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage must be connected). Data Validity As shown by fig. 22, the data on the SDA line must be stable during the high period of the clock. The HIGH and LOW state of the data line can only change when the clock signal on the SCL line is LOW ...
