1 / 29 page LM139AQML, LM139QML www.ti.com SNOSAH8G – FEBRUARY 2005 – REVISED MARCH 2013 LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS Check for Samples: LM139AQML, LM139QML 1 FEATURES • Compatible with all Forms of Logic • Power Drain Suitable for Battery Operation 2 • Available With Radiation Ensured – Total Ionizing Dose 100 krad(Si) DESCRIPTION – ELDRS Free 100 krad(Si) The LM139 series consists of four independent • Wide Supply Voltage Range precision voltage comparators with an offset voltage • LM139/139A Series 2 to 36 VDC or ±1 to ±18 VDC specification as low as 2 mV max for all four comparators. These were designed specifically to • Very Low Supply Current Drain (0.8 mA) — operate from a single power supply over a wide range Independent of Supply Voltage of voltages. Operation from split power supplies is • Low Input Biasing Current: 25 nA also possible and the low power supply current drain is independent of the magnitude of the power supply • Low Input Offset Current: ±5 nA voltage. These comparators also have a unique • Offset Voltage: ±1 mV characteristic in that the input common-mode voltage • Input Common-mode Voltage Range Includes range includes ground, even though operated from a GND single power supply voltage. • Differential Input Voltage Range Equal to the Application areas include limit comparators, simple Power Supply Voltage analog to digital converters; pulse, squarewave and • Low Output Saturation Voltage: 250 mV at 4 time delay generators; wide range VCO; MOS clock mA timers; multivibrators and high voltage digital logic gates. The LM139 series was designed to directly • Output Voltage Compatible with TTL, DTL, interface with TTL and CMOS. When operated from ECL, MOS and CMOS Logic Systems both plus and minus power supplies, they will directly interface with MOS logic— where the low power drain ADVANTAGES of the LM139/LM139A is a distinct advantage over standard comparators. • High Precision Comparators • Reduced VOS Drift Over Temperature • Eliminates Need for Dual Supplies • Allows Sensing Near GND 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
