LM139/LM239/LM339/LM2901/LM3302 Low Power Low Offset Voltage Quad Comparators November 1999 LM139/LM239/LM339/LM2901/LM3302 Low Power Low Offset Voltage Quad Comparators 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. n n n n n 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 Features n 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 n Very low supply current drain (0.8 mA) — independent of supply voltage n Low input biasing current: 25 nA ± 5 nA n Low input offset current: ± 3 mV n Offset voltage: n Input common-mode voltage range includes GND n Differential input voltage range equal to the power supply voltage n Low output saturation voltage: 250 mV at 4 mA n Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems Advantages n High precision comparators Connection Diagrams DS005706-27 Order Number LM139AW/883 or LM139W/883 (Note 1) LM139AWRQML and LM139AWRQMLV(Note 3) See NS Package Number W14B LM139AWGRQML and LM139AWGRQMLV(Note 3) See NS Package Number WG14A © 1999 National Semiconductor Corporation DS005706 www.national.com LM139/LM239/LM339/LM2901/LM3302 Connection Diagrams (Continued) Dual-In-Line Package DS005706-2 Order Number LM139J, LM139J/883 (Note 1), LM139AJ, LM139AJ/883 (Note 2), LM239J, LM239AJ, LM339J, LM139AJRQML and LM139AJRQMLV(Note 3) See NS Package Number J14A Order Number LM339AM, LM339M or LM2901M See NS Package Number M14A Order Number LM339N, LM339AN, LM2901N or LM3302N See NS Package Number N14A Note 1: Available per JM38510/11201 Note 2: Available per SMD# 5962-8873901 Note 3: See STD Mil Dwg 5962R96738 for Radiation Tolerant Device www.national.com 2 LM139/LM239/LM339/LM2901/LM3302 Absolute Maximum Ratings (Note 13) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
