LM139-N | Low-Power Low-Offset Voltage Quad Comparators |
The LM139 series consists of four independent precision voltage parators with an offset voltage specification as low as 2 mV max for all four parators. These 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 the low power supply current drain is independent of the magnitude of the power supply voltage.
