APPLICATION INFORMATION
1.Input Voltage
When the excessive signal is input, turning-up is produced in the clip waveform. The turning-up point is
Vin=300mVrms(Typical) at Vcc=9V,RL=4
f=1kHz. Enough care must be taken for this phenomenon.
2.Power ON/OFF
There is power ON/OFF switch at pin 1. However output power is changed by pin 1 supply voltage when
pin1 supply voltage is not same pin 12 supply voltage, after referring to attached date, select pin 1 supply voltage.
3.Voltage Gain
The voltage gain can be changed by the external negative feedback resistor. When Rf=0, the Gain is equal
to 56.5dB.When Rf=120
the Gain is equal to 45dB.
