LM339N Datasheet PDF – Quad Differential Comparator

Part Number: LM339N

Function: Quad single supply comparator

Package: DIP 8 Pin

Manufacturer: Texas Instruments


LM339N Quad Comparator



The LM139N series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. 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. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
