APPLICATION INFORMATION(Cont.)
4. OSCILLATION PREVENTIVE MEASURES
For oscillation preventive capacitor C6 and C7 between the output terminal and GND, polyester film capacitor is
recommended due to good characteristics for temperature and for high frequency. it is better that use this capacitor
after the temperature test to check the oscillation allowance due to the characteristics of the capacitor is liable to
be influenced by the temperature.Besides, as the position of the electrolytic capacitor has remarkable influence on
the oscillation, connect C10 to VCC as close power GND as possible.
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.
5. POWER ON/OFF SWITCH
There is power on/off switch at (3) pin. However, output power is changed by (3) pin supply voltage when(3) pin
supply voltage I not same(12) pin supply voltage, after referring to attached date, select(3) pin supply voltage.
6. INPUT VOLTAGE
When the excessive signal is input, turning-up is produced in the clip waveform. The turning-up point is
VIN=300mVrms (typ.): VCC=9V, RL=4Ω, f=1kHz: Enough care must be taken for this phenomenon.
7. GND LINE
GND pin is not separated for pre-GND and for PW-GND. That is liable to cause distortion and cross talk worse.
