AS393A

LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS General Description Features Data Sheet AS393/393A 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, TDIP-8, SOIC-8, TSSOP-8 and MSOP-8 packages, AS393A is available in standard DIP-8 and SOIC-8 packages. · 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 TDIP-8 Jan. 2013 Rev. 2. 3 TSSOP-8 MSOP-8 Figure 1.
