 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.
