2.4W AUDIO AMPLIFIER, SIF AMPLIFIER AND
DETECTOR FOR TV SILICON MONOLITHIC
BIPOLAR INTEGRATED DIRCUIT
DESCRIPTION
The CD1353CP is a silicon monolithic
integrated circuit designed for SIF and Audio
section in television receivers. This IC has
all functions including sound IF Amplifier,
FM Detector, DC volu me control circuit,
Audio Output amplifier with 2.4W output
power and voltage regulator.
This IC is encapsulated in 14pin dual
in-line package with heat tab.

FEATURES:
All function s for SIF and audio stage are provided by th is on e-chip IC and this IC
will realize reduction of asse mb l y cost as well as reduction of nu mb er of o ther
co mponents.
Audio outpu t po wer is controlled by electronic attenuation circuit which op erate
at DC. Therefore, unnecessary ra diation, oscillation etc. are eliminated . Due to
DC control, shielded wire is not required and variable resistor will be placed
anywhere required.
Electro nic attenu ator h as enough attenu ation (Typ.80dB) by the adoption of
squelch circuit. In addition, as attenuation characteristic is same with resistance
change of variable resistor, suitable variable resistor will be selected easily.
As Peak differential detection method is adopted for FM detection, outside
circuitry can be very simple easy.
As operation voltage (Vcc) range for output stage is very wide (9 -18V), suitable
Vcc can be freely determined for required output level.
