LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS  
AS393/393A  
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.  
·
Wide Supply Voltage Range  
- Single Supply: 2.0V to 36V  
- Dual Supplies: ±1.0V to ±18V  
Low Supply Current Drain: 0.6mA  
Low Input Bias Current: 25nA (Typical)  
Low Input Offset Current: ±5.0nA (Typical)  
Low Input Offset Voltage: 1.0mV (Typical)  
Input Common Mode Voltage Range Includes  
Ground  
·
·
·
·
·
The AS393/393A series are compatible with industry  
standard 393. AS393A has more stringent input offset  
voltage than AS393.  
·
Differential Input Voltage Range Equals to the  
Power Supply Voltage  
·
·
Low Output Saturation Voltage: 200mV at 4mA  
Open Collector Output  
The AS393 is available in standard DIP-8, SOIC-8  
TSSOP-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 Max-  
imum 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 V

Note 3: These specifications are limited to -40 C≤ TA ≤85 C. 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 V -1.5V (at 25oC), but either or  
CC  
both inputs can go to +18V without damages, independent of the magnitude of the V
