* As the oscillation allowance varies according to the printed pattern layout, the standard printed board of KEC is recommended
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 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 V
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.

When the excessive signal is input, turning-up is produced in the clip waveform.
The turning-up point is V
GND pin is not separated for Pre-GND and for Pw-GND. That is liable to cause distortion and cross talk worse.
Before use this IC, please check it.
