The TDA8190 is a complete TV sound channel with
DC tone and volume controls plus separate VCR
input and output connections. Mounted in a Pow-
erdip 16 + 2 + 2 package, the device delivers an
output power of 4W into 16鈩?(d = 10%, V
s
= 24V)
or 1.5W into 8鈩?(d = 10%, V
s
= 12V). Included in
the TDA8190 are : IF amplifier limiter, active low-
pass filter, AF pre-amplifier and power amplifier,
turn-off muting, mute circuit and thermal protection.
High output, high sensitivity, excellent AM rejection
and low distortion make the device suitable for use
in TVs of almost every type. Further, no screening
is necessarybecause the device is free of radiation
problems.
