TDA8190
TV SOUND CHANNEL WITH DC CONTROLS
........ SEPARATE VCR INPUT AND OUTPUT PINS
4W OUTPUT POWER INTO 16Ω
NO SCREENING REQUIRED
HIGH SENSITIVITY
EXCELLENT AM REJECTION
LOW DISTORTION
DC TONE/VOLUME CONTROLS
THERMAL PROTECTION
DESCRIPTION
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 16Ω (d = 10%, Vs = 24V)
or 1.5W into 8Ω (d = 10%, Vs = 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.
