2.4W AUDIO AMPLIFIER, SIF AMPLIFIER AND
DETECTOR FOR TV SILICON MONOLITHIC
BIPOLAR INTEGRATED DIRCUIT CD1353CP
DESCRIPTION Outline Drawing
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 volume 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 functions for SIF and audio stage are provided by this one-chip IC and this IC
will realize reduction of assembly cost as well as reduction of number of other
components.
Audio output power is controlled by electronic attenuation circuit which operate
at DC. Therefore, unnecessary radiation, oscillation etc. are eliminated. Due to
DC control, shielded wire is not required and variable resistor will be placed
anywhere required.
Electronic attenuator has 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.
