TA8703S
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8703S
QUASI-SIF SYSTEM FOR TV
FEATURES
l QUASI-SIF IC for TV
l 3-stage, gain-controlled intermediate frequency (IF) amplifier
The IF amplifier has three stages. Automatic gain control
(AGC) is used to control this 3-stage amplifier circuit.
l Doubled time constant for accelerated AGC response
l AGC is peak value type.
l AFT voltage is output single-polarity with a defeat function.
l RF-AGC supplied to the tuner is reverse type.
l White noise inverter circuit.

· TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices in general
can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the
buyer, when utilizing TOSHIBA products, to comply with the standards of safety in making a safe design for the entire system, and
to avoid situations in which a malfunction or failure of such TOSHIBA products could cause loss of human life, bodily injury or
damage to property.
In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the
most recent TOSHIBA products specifications. Also, please keep in mind the precautions and conditions set forth in the “Handling
Guide for Semiconductor Devices,” or “TOSHIBA Semiconductor Reliability Handbook” etc..
