APPLICATION EXAMPLE

NOTE FOR USE

•

ABOUT INPUT VOLTAGE

This IC’s VDD, VCC, VrefU1, VrefU2, VrefL1, VrefL2 pins must be supplied the stable voltage. When the voltage-

level of these pins are added any noise signal, the analog accuracy of output voltage may be influenced by

any noise signal.

Therefore, the bypass condenser is connected between these pins and GND pins for keeping the analog

accuracy. And it’s necessary that the bypass condenser is near IC.

•

HANDLING RELATED TO THE UNUSED PINS

The output pins have a possibility of being unused pins.

If there are unused pins, they must not be connected.
