This IC has the amplifier constructions as shown in Fig. 1. The Pre-Amp(Amp 1) is provided to the
primary stage, and the input voltage is amplified by the Flat Amps, Amp 3 and Amp 4 of each
channel through the phase Amp(Amp 2).
Since the input offset is prevented by Pre-Amp when VCC is set to ON, this circuit can remarkably
reduce the pop noise.

3. Preventive Measure Against Oscillation
For preventing the oscillation, it is advisable to use C4, the condenser of polyester film having small
characteristic fluctuation of the temperature and the frequency.
The condenser (C6) between input and GND is effective for preventing oscillation which is
generated with a feedback signal from a output stage.
The resistance R to be series applied to C4 is effective for phase correction of high frequency, and
improves the oscillation allowance.
(1) Voltage gain to be used (GV Setting)
(2) Capacity value of condenser
(3) Kind of condenser
(4) Layout of printed board
In case of its use with the voltage gain GV reduced or with the feedback amount increased, care
must be taken because the phase-inversion is caused by the high frequency resulting in making the
oscillation liable generated.
4. Adjustment of Output Offset (When the power supply turn on)
As this IC is constructed with DC circuit on the Pre-Amp stage, it is necessary to lower a input
offset or output offset by agreement with the each leading edge time constant of the input
voltage in the Pre-Amp stage and NF terminal voltage.
Concretely, monitor the output DC voltage and vary the capacity value in input condenser and NF
condenser (See Fig.4)

7. Rapid Ripple Discharging Circuit at the Time of VCC OFF

Low simultaneously ; for instance, for a pop noise produced when the power is turned ON or OFF
repeatedly by operating the ignition key.

TOSHIBA TA8233H
(Precaution 1)
When the stand-by terminal was put to the low level after the ripple
rapid discharging circuit was operated Nctyer81/) at the time when VCC
was turned OFF, a pop noise may be generated. Therefore, VCC which
makes the Stand-by terminal low shall be set at 8V or above so that
(1) the Stand-by terminal is put at the low level and (2) the ripple (Fig.9)
rapid discharging circuit is turned ON when VCC is turned OFF (in order
of (1) and (2)). An example of application is shown in Fig.9.
(Precaution 2)
If the falling time constant of the VCC line is large (the fall is gentle), the pop noise may become
worse.
In this case, it is possible to prevent the pop noise from becoming worse by reducing the ability of
"Ripple Rapid Discharging Circuit at the time of VCC OFF" according to the increase of the capacity
of ripple capacitor of pin..
However, it shall be kept in mind that the time for turning the power ON becomes longer as the
result of this method.
