Application Hints
GENERAL PRECAUTIONS
The LM359 is designed primarily for single supply operation
but split supplies may be used if the negative supply voltage
is well regulated as the amplifiers have no negative supply
rejection.
Typical Applications
• Eliminates the need for an input coupling capacitor
• Input DC level must be stable and can exceed the supply voltage of the LM359 provided that maximum input currents are not
exceeded.

The total device power dissipation must always be kept in
mind when selecting an operating supply voltage, the pro-
gramming current, I
when DC coupling the output to a succeeding stage. To pre-
vent damaging the current mirror input diode, the mirror cur-
rent should always be limited to 10 mA, or less, which is im-
portant if the input is susceptible to high voltage transients.
The voltage at any of the inputs must not be forced more
negative than −0.7V without limiting the current to 10 mA.
The supply voltage must never be reversed to the device;
however, plugging the device into a socket backwards would
then connect the positive supply voltage to the pin that has
no internal connection (pin 5) which may prevent inadvertent
device failure.
