Features Wide supply voltage range   LM139/139A Series 2 to 36 VDC or ±1 to ±18 VDC LM2901: 2 to 36 VDC or ±1 to ±18 VDC LM3302: 2 to 28 VDC or ±1 to ±14 VDC 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   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. Applications • High precision comparators • Reduced VOS drift over temperature • Eliminates need for dual supplies • Allows sensing near GND • Compatible with all forms of logic • Power drain suitable for battery operation

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
