Product Summary

The LM339N is a Low Power Low Offset Voltage Quad Comparator. The LM339N consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. The device is 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 LM339N also has a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas of the LM339N 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.

Parametrics

LM339N absolute maximum ratings: (1)Supply Voltage, V+: 36 VDC or ±18 VDC; (2)Differential Input Voltage: 36 VDC; (3)Input Voltage: -0.3 VDC to +36 VDC; (4)Input Current (VIN<-0.3 VDC): 50 mA; (5)Power Dissipation: 1050 mW; (6)Storage Temperature Range: -65 to +150℃; (7)Lead Temperature (Soldering, 10 seconds): 260℃; (8)Operating Temperature Range: 0 to +70℃; (9)Soldering Information: 260℃.

Features

LM339N features: (1)Wide supply voltage range; (2)Very low supply current drain (0.8 mA) — independent of supply voltage; (3)Low input biasing current: 25 nA; (4)Low input offset current: ±5nA; (5)Offset voltage: ±3mV; (6)Input common-mode voltage range includes GND; (7)Differential input voltage range equal to the power supply voltage; (8)Low output saturation voltage: 250 mV at 4 mA; (9)Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems.
