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.
