Low Offset Voltage
Dual Comparators
The LM393 series are dual independent precision voltage
comparators capable of single or split supply operation. These devices
are designed to permit a common mode rangetoground 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 SingleSupply Range: 2.0 Vdc to 36 Vdc
SplitSupply 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) LM293/393
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
ESD Clamps on the Inputs Increase the Ruggedness of the Device
without Affecting Performance
NCV Prefix for Automotive and Other Applications Requiring Site
