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 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) 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 and Control Changes

• Pb−Free Packages are Available

MAXIMUM RATINGS

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.

1. The maximum output current may be as high as 20 mA, independent of the magnitude of V_CC, output short circuits to V_CC can cause excessive heating and eventual destruction.

2. NCV2903 is qualified for automotive use.

3. V_ESD rating for NCV/SC devices is: Human Body Model − 2000 V; Machine Model − 200 V.
