Product Summary

The LM339 is a low power low offset voltage quad comparator. The LM339 consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. The LM339 was 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. The comparator LM339 also has a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

Parametrics

LM339 absolute maximum ratings: (1)Power Dissipation Molded DIP: 1050 mW; (2)Cavity DIP: 1190 mW; (3)Small Outline Package: 760 mW; (4)Output Short-Circuit to GND: Continuous Continuous; (5)Storage Temperature Range: -65℃ to +150℃; (6)Lead Temperature: 260℃; (7)Operating Temperature Range: -40℃ to +85℃; (8)Dual-In-Line Package Soldering: 260℃; (9)Small Outline Package Vapor Phase (60 seconds): 215℃; (10)Infrared (15 seconds): 220℃; (11)ESD rating (1.5 kΩ in series with 100 pF): 600V.
