LOW POWER DUAL DIFFERENTIAL COMPARATOR
Description
The GM393 consist of two independent precision voltage
comparators with an offset voltage specification as low as
2.0 mV, max for two comparators which were designed spe-
cifically 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 in-
dependent 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; multivi-
brators 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.
Features
Single- supply Range: ±1.0V to ±18V
Wide supply voltage range: ±2.0V to ±36V
Very low supply current drain (0.4 mA) -
independent of supply voltage
Low input biasing current: 25 nA
Low input offset current: ±5 nA
Maximum offset voltage: ±3 mV
Input common-mode voltage range includes
ground
Differential input voltage range equal to the
power supply voltage
Low output saturation voltage: 250 mV at 4 mA
Output voltage compatible with TTL, DTL, ECL,
MOS and CMOS logic systems
Application
High precision comparators
Reduced VOS drift over temperature
Eliminates need for dual supplies
Allows sensing near GND
Compatible with all forms of logic
Power drain suitable for battery operation
