AS393
AS393/393A
LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS
Description
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 PDIP-8, SO-8, TSSOP-8 and
MSOP-8 packages, AS393A is available in standard PDIP-8 and SO-
8 packages.

4. 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.
5. 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 +25°C).
