The TDA3190 is a monolithic integrated circuit in a
16-lead dual in-line plastic package. It performs all
the functions needed for the TV sound channel :
.
IF LIMITER AMPLIFIER
.
ACTIVE LOW-PASS FILTER
.
FM DETECTOR
.
DC VOLUME CONTROL
.
AF PREAMPLIFIER
.
AF OUTPUT STAGE
DESCRIPTION
The TDA3190 can give an output power of 4.2 W
(d = 10 %) into a 16
load at V
S
= 24 V, or 1.5 W
(d = 10 %) into an 8
load at V
S
= 12 V. This
performance, together with the FM-IF section char-
acteristics of high sensitivity, high AM rejection and
low distortion, enables the device to be used in
almost every type of television receivers.
The device has no irradiation problems, hence no
external screening is needed.
The TDA3190 is a pin to pin replacement of
TDA1190Z.

The electrical characteristics of the TDA3190 re-
main almost constant over the frequency range 4.5
to 6 MHz, therefore it can be used in all television
standards (FM mod.). The TDA3190 has a high
input impedance,so it can work with a ceramic filter
or with a tuned circuit that provide the necessary
input selectivity.
The value of the resistors connected to pin 9,
determine the AC gain of the audio frequency am-
plifier. This enables the desired gain to be selected
in relation to the frequency deviation at which the
output stage of the AF amplifier, must enter into
clipping.
Capacitor C8, connected between pins 10 and 11,
determines the upper cutoff frequency of the audio
bandwidth. To increase the bandwidth the values of
C8 and C7 must be reduced, keeping the ratio
C7/C8 as shown in the table of fig. 16.
The capacitor connecte d between pin 16 and
ground, together with the internal resistor of 10 K
forms the de-emphasis network. The Boucherot
cell eliminates the high frequency oscillations
caused by the inductiveload and the wires connect-
ing the loudspeaker.

The Rth j-amb of the TDA3190 can be reduced by
soldering the GND pins to a suitable copper area
of the printed circuit board (fig. 18) or to an external
heatsink (fig. 19).
The diagram of figure 20 shows the maximum
dissipable power Ptot and the Rth j-amb as a func-
tion of the side "l" of two equal square copper areas
having a thickness of 35
(1.4 mils).
During soldering the pins temperature must not
exceed 260
C and the soldering time must not be
longer than 12 seconds.
The external heatsink or printed circuit copper area
must be connected to electrical ground.
