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.
