2. THERMAL SHUT-DOWN CIRCUIT
The thermal shut-down circuit is built in for the purpose of preventing the
destruction of IC due to the abnormal temperature rise when the heat radiation is
insufficient . The operation temperature is set at radiation Fin temperature
175°C(Typ.)
At this temperature or over the bias is interrupted to prevent the destruction of
IC.
3. INPUT STAGE
The input circuit of this IC is as shown
in Fig.2.PNP TR: Q1 is provided in the
input circuit so as to make its usage.
Possible without the input coupling
capacitor. However , at pins ⑥ and
⑦ ,max 60mV offset voltage is produced.
Application after checking volume slide

4. OSCILATION PREVENTIVE MEASURES
Fig.2
For oscillation preventive capacitor C6 and C7 between the output terminal and
GND ,it is 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 C10 to Vcc at the nearest possible position
from power GND.
At using this application with the voltage gain reduced, oscillation is liable to be
produced ,Apply the capacitor after checking enough for its capacity ,type and
mounting position.
