Data Sheet
LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS
General Description
Features
The AS393/393A consist of two independent precision
voltage comparators with a typical offset voltage of
1.0mV and high gain. They are specifically designed to
operate from a single power supply over wide range of
voltages. Operation from split power supply is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.
·
·
·
·
·
·
The AS393/393A series are compatible with industry
standard 393. AS393A has more stringent input offset
voltage than AS393.
·
·
·
The AS393 is available in standard DIP-8, TDIP-8,
SOIC-8, TSSOP-8 and MSOP-8 packages, AS393A is
available in standard DIP-8 and SOIC-8 packages.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability.
Note 2: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to
the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode
clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This
transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground for a
large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output
states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3 VDC
(at 25oC).

Note 3: These specifications are limited to -40oC≤ TA ≤85oC. Limits over temperature are guaranteed by design,
but not tested in production.
Note 4: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by
more than 0.3V (at 25oC). The upper end of the common-mode voltage range is VCC-1.5V (at 25oC), but either or
both inputs can go to +36V without damages, independent of the magnitude of the VCC.
