Product specification
TV sound AM-demodulator and audio source switch
TDA9830
pin 8. The decoupling capacitors at
the input pins are needed, because
the internally generated bias voltage
for the input stages must not be
influenced by the application in order
to avoid DC-plop in case of switching.
The AM demodulator output is
designed to provide almost the same
DC voltage as the input bias voltage
of the audio switch. But there may be
spread between both voltages.
Therefore it is possible to connect pin
6 directly to pin 7 (without a
decoupling capacitor), but in this
event the DC-plop for switching can
increase up to 100 mV.
Reference circuit
This circuit is a band gap stabilizer in
combination with a voltage regulation
amplifier, which provides an internal
reference voltage of about 3.6 V
nearly independent from supply
voltage and temperature. This
reference voltage is filtered by the
capacitor at pin 4 in order to reduce
noise. It is used as a reference to
generate all important voltages and
currents of the circuit.
For application in 12 V power supply
concepts, there is an internal voltage
divider in combination with a
Darlington transistor in order to
reduce the supply voltage for all IC
function blocks to approximately 6 V.
This is necessary because of use of
modern high frequency IC
technology, where most of the used
integrated components are only
allowed to operate at maximum 9 V
supply voltage.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC134).
Note to the limiting values
1.
To avoid an inadmissible increase of ambient temperature, it is not allowed to short-circuit pin 11 for more than 10
seconds to ground.
