	Everyone should READ the application notes for the parts you use.

	The manufacturer and original designer National Semiconductor
suggest:

	Decouple power supplies
	Twist power supply leads tightly
	And the use of a series 0.1 mF cap and 5 ohm resistor from output
to ground.  This is Required to prevent oscillation.

	It may require a 1.0 cap and 2 0hm resistor in the design in the
URL as there appears to be NO suggestion of power supply decoupling.
