LM393S Datasheet, PDF (1/6 Pages) ON Semiconductor – Low Offset Voltage Dual Comparators
LM393S, LM2903S
Low Offset Voltage
Dual Comparators
The LM393S and LM2903S are dual, independent, precision
voltage comparators capable of single or split supply operation. These
devices are designed to permit a common mode range to ground level
with single supply operation. Input offset voltage specifications as low
as 2.0 mV make this device an excellent selection for many
applications in consumer, automotive, and industrial electronics.
Features
• Wide Single−Supply Range: 2.0 Vdc to 36 Vdc
• Split−Supply Range: ±1.0 Vdc to ±18 Vdc
• Very Low Current Drain Independent of Supply Voltage: 0.4 mA
• Low Input Bias Current: 25 nA
• Low Input Offset Current: 5.0 nA
• Low Input Offset Voltage: 5.0 mV (max) with LM393S
• Input Common Mode Range to Ground Level
• Differential Input Voltage Range Equal to Power Supply Voltage
• Output Voltage Compatible with DTL, ECL, TTL, MOS, and CMOS
Logic Levels
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
