DESCRIPTION
The TDA3190 can give an output power of 4.2 W (d = 10 %) into a 16 load at V (d = 10 %) into an 8 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.

APPLICATIONINFORMATION
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

clipping. CapacitorC8, connectedbetween pins10 and11,
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 10K 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).

which is used as Heatsink
havinga thicknessof 35 µ (1.4mils). During soldering the pins temperature must not
exceed 260°C andthe solderingtime must not be longer than 12 seconds.
