| Data Sheet LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS AZ393/393C General Description 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 voltage. 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. The AZ393/393C series is designed to directly interface with TTL and CMOS. AZ393C has more stringent input offset voltage than AZ393. Features * 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 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 applications such as battery charger, cordless telephone, switching power supply, DC-DC module and PC motherboard. The AZ393/393C series are available in standard packages of DIP-8 and SOIC-8.

Aug. 2006 Rev. 1. 2 3 BCD Semiconductor Manufacturing Limited Data Sheet LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS AZ393/393C Absolute Maximum Ratings (Note 1) Parameter Supply Voltage Differential Input Voltage Input Voltage Input Current (VIN < -0.3V) (Note 2) Power Dissipation (TA=25oC) Output Short Circuit to Ground Operating Junction Temperature TJ TSTG TLEAD Symbol VCC VID VIN IIN Value 20 20 -0.3 to 20 50 DIP-8 780 660 150 Unit V V V mA mW PD SOIC-8 Continuous o C Storage Temperature Range Lead Temperature (Soldering, 10 seconds) -65 to 150 260 oC o C 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 4: The direction of the input current is out of the PNP input stage. This current is essentially constant, independent 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 VCC-1.5V, but either or both inputs can go to +18V without damage, independent of the magnitude of VCC. Note 6: The response time specified is a 100mV input step with 5mV overdrive. For large overdrive signals 300ns can be obtained.
