	~~asdf~~		=== Introduction ===
			Basic operational amplifier (op amp) circuits are covered to death elsewhere. What is commonly not discussed, however, is that real-world (industrial, rugged) op amp circuits are NOT the basic ones commonly shown everywhere.

			=== Real-World Op Amp Circuit Considerations ===
			Real-world considerations (for an op amp in an industrial / commercial product) include the following:

			# Provisions to prevent op amp from oscillation.
			# Provisions to include filtering on op am input.
			# Provisions to balance op amp input impedances, especially when filtering is employed.
			# Picking an appropriate op amp IC type for the project at hand.
			# And many others.
