DESCRIPTION
TheTDA8190isa completeTVsoundchannelwith
DC tone and volume controls plus separate VCR
input and output connections.Mounted in a Powerdip 16 + 2 + 2 package,the device delivers an
output power of4W into 16Ω (d= 10%, V
or 1.5Winto 8Ω (d= 10%, V
the TDA8190 are : IF amplifier limiter, active lowpass filter, AF pre-amplifier and power amplifier,
turn-offmuting,mutecircuitandthermalprotection.
High output,highsensitivity,excellentAM rejection
and lowdistortionmake the devicesuitablefor use
in TVs of almostevery type. Further,no screening
is necessarybecausethe deviceis free of radiation
problems.
