1 / 20 page LM139JAN Low Power Low Offset Voltage Quad Comparators General Description The LM139 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 gen- erators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM139 was de- signed to directly interface with TTL and CMOS. When op- erated from both plus and minus power supplies, they will directly interface with MOS logic — where the low power drain of the LM139 is a distinct advantage over standard comparators. Features n Wide supply voltage range 5V to 36 V DC or ±2.5V to ±18 V DC n Very low supply current drain (0.8 mA) — independent of supply voltage n Low input biasing current: 25 nA n Low input offset current: ±5nA n Offset voltage: ±3mV 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 n Reduced V OS drift over temperature n Eliminates need for dual supplies n Allows sensing near GND n Compatible with all forms of logic n Power drain suitable for battery operation Ordering Information NS Part Number JAN Part Number NS Package Number Package Description JL139BCA JM38510/11201BCA J14A 14LD CERDIP JL139SCA JM38510/11201SCA J14A 14LD CERDIP JL139BZA JM38510/11201BZA WG14A 14LD Ceramic SOIC JL139SZA JM38510/11201SZA WG14A 14LD Ceramic SOIC JL139BDA JM38510/11201BDA W14B 14LD CERPACK JL139SDA JM38510/11201SDA W14B 14LD CERPACK February 2005 © 2005 National Semiconductor Corporation DS201295 www.national.com |
