Low Power Low Offset Voltage Dual Comparators

General Description

The LM193 series consists of two independent precision

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.

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 LM193 series was

designed to directly interface with TTL and CMOS. When

operated from both plus and minus power supplies, the

LM193 series will directly interface with MOS logic where

their low power drain is a distinct advantage over standard

comparators.
