APPLICATION HINTS
This section explains briefly how to get the best
from the TDA7350A and presents some applica-
tion circuits with suggestions for the value of the
components.Thesevalues can change depending
on the characteristicsthat the designer of the car
radio wants to obtain,or other parts of the car ra-
dio that are connectedto the audio block.
To optimizethe performanceof the audio part it is
useful (or indispensable)to analyzealso the parts
outside this block that can have an interconnec-
tion with the amplifier.
This methodcan provide componentsand system
costsaving.
Reducing Turn On-Off Pop
The TDA7350A 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 spec-
trum 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
appearsto 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,doesnot givepop effect).
TURN-ON
Fig. 39 shows the output waveform (before and
after the ”A” weighting filter) compared to the
value of Csvr.
Better pop-on performance is obtained with
higher Csvr values (the recommended range is
from22uF to 220uF).
The turn-on delay (during which the amplifieris in
mute condition) is a function essentially of : C

The best performance is obtained by driving the
st-by pin with a ramp having a slope slower than
