APPLICATION INFORMATION AND APPLICATION METHOD
1. ADJUSTMENT 0F VOLTAGE GAIN
The voltage gain Gv ls obtained as
follows by RI, R2 and Rf Fig.1.
Rf+R1+R2
Gv=202og Rf+R1
When Rf=0 GV=56dB(Typ.)
When anszn, Gv=45dB(Typ.)
By increasing Rf, reduction of CV is
possible. However, since the feedback Fig. 1
Increase ls liable to produce oscillation,
it is recommended to use this at 40dB or over.
2. THERMAL SHUT-DOWN CIRCUIT
The thermal shut-down circuit Is built in for the purpose of prevehting the
destruction of IC due to the abnormal temperature rise when the heat tadiation
ls insufficient.
The operation temperature ls set at radiation Fin temperature 175''C (Typ.).
At this temperature or over the bias ls interrupted to prevent the destruction
of IC.
3. INPUT STAGE
The Input circuit of this
IC ls as shown is Fig.2.
PNP Ter1 ls provided In
the input circuit so as

However, at pins GDand Q),

is produced. a

Application after checking volume slide noise ls recommended.
For cutting the volume slide noise, insert the Input capacitor:C1n in series to
Interrupt the DC compornent.
4. OSCILLATION PREVENTIVE MEASURES
. For escillation preventive capacitor-Cé and C7 between the output terminal and
GND, it ls recommended to use polyester film capacitor having good characteristics
for temperature and for high frequency.
Since the characteristics of the capacitor is liable to be Influenced by the
temperature, use this capacitor after the temperature test to check the
oscillation'allowance.
In addition, as the position of the electrolytic capacitor has a remarkable
influence on the oscillation, connect CIO to VCC at the nearest possible position
from bower GND.
At using this application with the voltage gain reduced, oscillation is liable to
be produced. jApply the capacitor after cheking enough for its capacity, type and
mounting position.
As the oscillation allowance varies according to the printed pattern layout,
the standard printed board of TOSHIBA ls recommended to be referred to for
design it.
5. INPUT VOLTAGE
When the excessive signal ls Input, turning-up ts produced in the clip waveform.
The turning-up point ls 1ltte300mVrms(iyp.)sVctr91r, RL=40, f=1kHz:Enough care must
be taken for this phenomenon.
