Opamp voltage supply
Any opamp can be operated from a single supply, as long as the circuit is arranged properly. 

Some amplifiers are advertised as 'single rail', when they have an input common mode range and an output swing that includes the negative rail. This feature often simplifies the circuit when using the negative rail as ground.

Some circuits lend themselves more easily to being referred to a 'ground' at mid supply, or the negative supply, or a less well-defined level between the rails.
