COMPLETE TV SOUND CHANNEL
The TDA3190is a monolithicintegratedcircuitin a
16-leaddual in-lineplastic package. Itperformsall
the functionsneededfor theTV soundchannel :
.
IF LIMITER AMPLIFIER
.
ACTIVELOW-PASSFILTER
.
FM DETECTOR
.
DC VOLUMECONTROL
.
AF PREAMPLIFIER
.
AF OUTPUT STAGE
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.
