LM139/LM239/LM339/LM2901/LM3302 March 2004 LM139/LM239/LM339/LM2901/LM3302Low Power Low Offset Voltage Quad ComparatorsGeneral Description Features The LM139 series consists of four independent precision n Wide supply voltage range voltage comparators with an offset voltage specification as n LM139/139A Series 2 to 36 V or ±1 to ±18 V DC DC low as 2 mV max for all four comparators. These were n LM2901: 2 to 36 V or ±1 to ±18 V DC DC designed specifically to operate from a single power supply n LM3302: 2 to 28 V or ±1 to ±14 V DC DC over a wide range of voltages. Operation from split power n Very low supply current drain (0.8 mA) -- independent supplies is also possible and the low power supply current of supply voltage drain is independent of the magnitude of the power supply n Low input biasing current: 25 nA voltage. These comparators also have a unique characteris-tic in that the input common-mode voltage range includes n Low input offset current: ±5 nA ground, even though operated from a single power supply n Offset voltage: ±3 mV voltage. n Input common-mode voltage range includes GND Application areas include limit comparators, simple analog to n Differential input voltage range equal to the power digital converters; pulse, squarewave and time delay gen- supply voltage erators; wide range VCO; MOS clock timers; multivibrators n Low output saturation voltage: 250 mV at 4 mA Low and high voltage digital logic gates. The LM139 series was n Output voltage compatible with TTL, DTL, ECL, MOS designed to directly interface with TTL and CMOS. When and CMOS logic systems operated from both plus and minus power supplies, they willdirectly interface with MOS logic -- where the low power Advantages Power drain of the LM339 is a distinct advantage over standard
