3 Description
The LM193-N series consists of two independent
precision voltage comparators with an oset voltage
specication as low as 2.0 mV max for two
comparators which were designed specically 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 i ncludes 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; multiv ibrators 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 direct ly 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.
