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.
