Dual Differential Comparators

LM393

n Reduced V_OSdrift over temperature

n Eliminates need for dual supplies

n Allows sensing near ground

n Compatible with all forms of logic

n Power drain suitable for battery operation

General Description

consists of two independent precision

The LM393

voltage comparators with an offset voltage specification as

low as 2.0 mV max for two comparators which were de-

signed 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.
