| Data Sheet LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS General 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 DIP-8, SOIC-8 TSSOP-8 packages, AS393A is available in standard DIP-8 and SOIC-8 packages. AS393/393A Features * 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 Differential Input Voltage Range Equals to the Power Supply Voltage Low Output Saturation Voltage: 200mV at 4mA Open Collector Output * * * * * * * * Applications * * * * * * Battery Charger Cordless Telephone Switching Power Supply DC-DC Module PC Motherboard Communication Equipment SOIC-8 DIP-8 TSSOP-8 Figure 1.

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).

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 +18V without damages, independent of the magnitude of the VCC.
