LINEAR INTEGRATED CIRCUIT
NOTES FOR USE(Cont.)
9. Ground Wiring Pattern
When using both small signal and large current GND patterns, it is recommended to isolate the two ground
patterns, placing a single ground point at the ground potential of application so that the pattern wiring resistance
and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be
careful not to change the GND wiring pattern of any external components, either.
10. Damage to the internal circuit or element may occur when the polarity of the VCC pin is opposite to that of
the other pins in applications. (I.e. VCC is shorted with the GND pin while an external capacitor is charged.)
Use a maximum capacitance of 1000μF for the output pins. Inserting a diode to prevent back-current flow in
series with VCC or bypass diodes between VCC and each pin is recommended.
