LM393 -Low Power Low Offset Voltage Dual Comparator

LM393: High-Performance Low Power Dual Voltage Comparator IC

The LM393 is a versatile low power dual voltage comparator integrated circuit. It features two independent comparators designed for reliable operation. This IC can function efficiently from a single power supply across a wide voltage range. Dual supply operation is also possible, supporting 2 V to 36 V differences. Its current drain remains independent of the supply voltage, ensuring stable performance. The outputs are open-collector, allowing for wired-AND configurations. This makes the LM393 an excellent choice for various sensing and control applications. It delivers consistent performance with low input bias and offset characteristics.
