LM393N Datasheet

Dual Differential Comparators


General Description
consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which 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 characteris
tic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

Wide supply
— Voltage range: 2.0V to 36V
— single or dual supplies: ±1.0V to ±18V
Very low supply current drain (0.4 mA) — independent of supply voltage
Low input biasing current: 25 nA
Low input offset current: ±5 nA
Maximum offset voltage: ±9mV
Input common-mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Low output saturation voltage,:  150mV at 4mA
Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems
