Description
The LM339 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.
Application areas include limit comparators, simple analog to
digital converters; pulse, squarewave and time delay
generators; wide range VCO; MOS clock timers;
multivibrators and high voltage digital logic gates. The LM339
was designed to directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, they will
directly interface with MOS logic — where the low power
drain of the LM339 is a distinct advantage over standard
comparators.
Features
• Wide supply voltage range
• LM339 is 2 to 36 VDC or – 1 to – 18

independent of supply voltage
• Low input biasing current: 25 nA
• Low input offset current: – 5 nA n Offset
voltage: – 3 mV
• Input common- mode voltage range
includes GND
• Differential input voltage range equal to the
power supply voltage
• Low output saturation voltage: 250 mV at 4
mA
• Output voltage compatible with TTL, DTL,
ECL, MOS and CMOS logic systems
