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.
