Application hints
This section explains briefly how to get the best from the TDA7360 and presents some
application circuits with suggestions for the value of the components.These values can
change depending on the characteristics that the designer of the car radio wants to obtain,
or other parts of the car radio that are connected to the audio block.
To optimize the performance of the audio part it is useful (or indispensable) to analyze also
the parts outside this block that can have an interconnection with the amplifier.
This method can provide components and system cost saving.
Reducing turn on-off pop
The TDA7360 has been designed in a way that the turn-on (off) transients are controlled
through the charge (discharge) of the Csvr capacitor.
As a result of it, the turn-on (off) transient spectrum contents is limited only to the subsonic
range.The following section gives some brief notes to get the best from this design feature (it
will refer mainly to the stereo application which appears to be in most cases the more critical
from the pop viewpoint.The bridge connection in fact, due to the common mode waveform at
the outputs, does not give pop effect).

the value of C
Better pop-on performance is obtained with higher C
from 22μF to 220μF).
The turn-on delay (during which the amplifier is in mute condition) is a function essentially
of: C
The turn-on delay is given by:
The best performance is obtained by driving the st-by pin with a ramp having a slope slower
than 2V/ms.
