LM393,LM293,LM2903,LM2903V,NCV2903 low offset voltage dual comparators 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.
The LM393 series and related parts are dual independent precision voltage comparators offered by ON Semiconductor. They operate from single or split supplies, feature low offset voltage and low input bias current, and are available in several package styles.
