Product specification IC11 Data Handbook 1995 Nov 27
Quad voltage comparator
The LM139 series consists of four independent precision voltage comparators, with an offset voltage specification as low as 2.0mV max for each comparator, which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and .
