Description

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 rangetoground 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 consists of two independent low power voltage comparators designed specifically to operate from a single supply over a wide range of voltages.

The absolute maximum ratings of the LM393 can be summarized as:(1):the symbol is Vcc,the parameter is supply voltage,the rating is ±18 or 36,the unit is V;(2):the symbol is VId,the parameter is differential input voltage,the rating is ±36,the unit is V;(3):the symbol is VI,the parameter is input voltage,the rating is -0.3 to +36,the unit is V;(4):the parameter is output short-circuit to ground,the rating is infinite;(5):the symbol is Ptot,the parameter is power dissipation,the rating is 830,the unit is mW;(6):the symbol is Toper,the parameter is operating free-air temperature range,the rating is 0 to +70,the unit is ;(7):the symbol is Tstg,the parameter is storage temperature range,the rating is 65 to +150,the unit is .
