Catalysis of the hydrolysis of a pyrophosphate bond between two phosphate groups, leaving one phosphate on each of the two fragments. Catalysis of the reaction: a nucleoside triphosphate + H2O = nucleoside diphosphate + phosphate. Catalysis of the reaction: ATP + H2O = ADP + phosphate to directly drive some other reaction, for example ion transport across a membrane. Catalysis of the reaction: ATP + H2O = ADP + phosphate; not directly coupled to any other reaction. Catalysis of the reaction: ATP + H2O = ADP + phosphate. May or may not be coupled to another reaction.
