General Description

The LM139 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.

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 LM139 series 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
LM139/139A Series	2 to 36 V_DC or ±1 to ±18 V_DC
LM2901:	2 to 36 V_DC or ±1 to ±18 V_DC
LM3302:	2 to 28 V_DC or ±1 to ±14 V_DC
Very low supply current drain (0.8 mA) - independent of supply voltage
Low input biasing current:	25 nA
Low input offset current:	±5 nA
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

Applications

High precision comparators
Reduced V_OS drift over temperature
Eliminates need for dual supplies
Allows sensing near GND
Compatible with all forms of logic
Power drain suitable for battery operation
