LM139JAN

Low Power Low Offset Voltage Quad Comparators

General Description

Features

n Wide supply voltage range

5V to 36 V_DCor 2.5V to

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.

18 V_DC

n Very low supply current drain (0.8 mA) — independent

of supply voltage

n Low input biasing current:

n Low input offset current:

25 nA

5 nA

3 mV

n Offset voltage:

n Input common-mode voltage range includes GND

n Differential input voltage range equal to the 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.

n Low output saturation voltage:

n Output voltage compatible with TTL, DTL, ECL, MOS

and CMOS logic systems

250 mV at 4 mA

Advantages

n High precision comparators

n Reduced V_OSdrift 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
