Data Sheet LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS General Description The AS339/339A consist of four independent precision voltage comparators with a typical offset voltage of 2.0mV 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 AS339/339A series are compatible with industry standard 339. AS339A has more stringent input offset voltage than AS339. The AS339 is available in DIP-14, SOIC-14 and TSSOP-14 packages, AS339A is available in DIP-14 and SOIC-14 packages AS339/339A Features · Wide Supply Voltage Range - Single Supply: 2.0V to 36V - Dual Supplies: ±1.0V to ±18V Low Supply Current Drain: 0.9mA Low Input Bias Current: 25nA (Typical) Low Input Offset Current: ±5.0nA (Typical) Low Input Offset Voltage: 2.0mV (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 DIP-14 SOIC-14 TSSOP-14 Figure 1.
