Dual Differential Comparators

LM393

DESCRIPTION：

The LM393 consists of two independent voltage

comparators with an offset voltage specification as low as

2.0mV max.for two comparators which were designed

specifically to operation from a single power supply over a

wide range of voltages. Operate 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.

FEATURE：

Wide supply voltage range：single supply operation：2V to

36V dual supply operation：±1V to ±18V

LM393D

Very low supply current drain (0.8m,A) independent of

supply voltage(2.0mW/comparator at 5.0 VDC)

Low input biasing current：25nA

Low input offset current：5.0nA; Low input offset voltage：

5.0mV

Input common-mode voltage range includes ground

SOP8

Differential input voltage range equal to the power supply voltage

Output voltage compatible with TTL,DTL,ECL,MOS and CMOS logic systems.
