GM393
LOW POWER DUAL
DIFFERENTIAL COMPARATOR
Description
The GM393 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,
square wave and time delay generators; wide
range VCO; MOS clock timers; multivibrators
and high voltage digital logic gates. The GM393
are designed to directly interface with TTL and
CMOS. When operated from both plus and
minus power supplies, the GM393 will directly
interface with MOS logic, where their low power
drain is a distinct advantage over standard
comparators.
The GM393 is available in DIP-8 and SOP-8
packages.
