The LM193-N 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-N series was designed to directly interface with TTL and
CMOS. When operated from both plus and minus power supplies, the LM19-N series will directly
interface with MOS logic where their low power drain is a distinct advantage over standard
comparators.The LM393 and LM2903 parts are available in TI’s innovative thin DSBGA package with 8 (12
mil) large bumps.
