GAMMA GM393

GM393
LOW POWER DUAL
DIFFERENTIAL COMPARATOR
Description
Features
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 commonmode voltage range includes ground, even
though operated from a single power supply
voltage.
‹
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
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.
‹
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
The GM393 is available in DIP-8 and SOP-8
packages.

All characteristics are measured under open loop conditions with zero common-mode input voltage unless otherwise specified.
"MAX" VCC for testing purposes is 30V. Full range is 0°C to 70°C.
** The voltage at either input or common - mode should not be allowed to go negative by more than 0.3V. The upper end of the
common - mode voltage range is VCC - 1.5V, but either or both inputs can go to 30V without damage.

Note 1: CL includes probe and jig capacitance. The response time specified is the interval between the input step function and the
instant when the output crosses 1.4V.
