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 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.
Application areas include limit comparators, simple analog to digital converters; pulse,
squarewave and time delay generators; 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.
