LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS  
AZ393/393C  
General Description  
Features  
The AZ393/393C series consists of two independent  
precision voltage comparators with an offset voltage  
specification as low as 1mV. The input common mode  
voltage range of these comparators includes ground,  
even when operated from a single power supply volt-  
age. Operation from split power supplies is also possi-  
ble 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 18V  
- Dual Supplies: ±1.0V to ±9V  
Very Low Supply Current Drain: 0.4mA  
·
- Independent of Supply Voltage  
·
·
·
·
Low Input Bias Current: 25nA (Typical)  
Low Input Offset Current: ±5nA (Typical)  
Low Input Offset Voltage: ±1mV (Typical)  
Input Common Mode Voltage Range Includes  
Ground  
The AZ393/393C series is designed to directly inter-  
face with TTL and CMOS. AZ393C has more  
stringent input offset voltage than AZ393.  
·
Differential Input Voltage Range Equals to the  
Power Supply Voltage  
·
·
Low Output Saturation Voltage: 250mV at 4mA  
Open Collector Output  
The AZ393/393C series can be widely used in applica-  
tions such as battery charger, cordless telephone,  
switching power supply, DC-DC module and PC  
motherboard.  
Applications  
The AZ393/393C series are available in standard pack-  
ages of DIP-8 and SOIC-8.

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 out-  
put states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3

Note 4: The direction of the input current is out of the PNP input stage. This current is essentially constant, inde-  
pendent of the state of the output, so no loading charge exists on the reference of input lines.  
Note 5: The input common-mode voltage of either input signal voltage should not be allowed to go negative by  
more than 0.3V. The upper end of the common-mode voltage range is V -1.5V, but either or both inputs can go to  
CC  
+18V without damage, independent of the magnitude of V  
.

Note 6: The response time specified is a 100mV input step with 5mV overdrive. For large overdrive signals 300ns  
can be obtained.
