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.
