LM393N Description

Short technical summary and product information.

The LM393N from NXP Semiconductors is a low-power dual voltage comparator. It is designed to operate from a single supply voltage ranging from 2 V to 36 V, or from split power supplies of ±1 V to ±18 V. This comparator features a very low supply current of 0.45 mA, independent of the supply voltage.

 

Key electrical characteristics include a low input bias current of 20 nA typical and a low input offset current of ±3 nA typical. The input offset voltage is also low at ±1 mV typical. The input common-mode voltage range includes ground, even when operated from a single power supply. The output saturation voltage is 80 mV typical when sinking 4 mA.

 

The LM393N is available in multiple package types including SO-8, TSSOP8, DIP8, MiniSO-8, and DFN8 2x2mm. Its wide operating temperature range and robust design make it suitable for various industrial and commercial applications.
