he 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.
