DESCRIPTION
The TDA3190 can give an output power of 4.2 W
(d = 10 %) into a 16 Ω load at V
(d = 10 %) into an 8 Ω load at V
performance,togetherwiththeFM-IFsectionchar-
acteristicsofhigh sensitivity, highAMrejection and
low distortion, enables the device to be used in
almost everytype of televisionreceivers.
The device has no irradiation problems,hence no
externalscreening is needed.
The TDA3190 is a pin to pin replacement of
TDA1190Z.

* Obtainedwith the GND pins soldered toprinted circuit with minimizedcopper area.
The electrical characteristics of the TDA3190 remainalmost constantoverthefrequencyrange 4.5
to 6 MHz, thereforeit can be used in all television
standards (FM mod.). The TDA3190 has a high
inputimpedance,so it canworkwithaceramicfilter
or with a tuned circuit that provide the necessary
input selectivity.
The value of the resistors connected to pin 9,
determinethe AC gainof the audio frequencyamplifier. This enablesthe desiredgain tobe selected
in relation to the frequency deviation at which the
output stage of the AF amplifier, must enter into
determinesthe uppercutofffrequencyofthe audio
bandwidth.Toincreasethebandwidththe valuesof
C8 and C7 must be reduced, keeping the ratio
C7/C8 as shown in thetable of fig. 16.
The capacitor connected between pin 16 and
ground,togetherwith theinternalresistorof 10KΩ
forms the de-emphasis network. The Boucherot
cell eliminates the high frequency oscillations
causedbythe inductiveloadandthewiresconnecting theloudspeaker.

MOUNTING INSTRUCTION
The Rthj-amb of the TDA3190can be reduced by
soldering the GND pins to a suitablecopper area
ofthe printed circuitboard (fig.18)or toan external
heatsink(fig. 19).

During soldering the pins temperature must not
exceed 260°C andthe solderingtime must not be
longer than 12 seconds.
