LM393N Description

Short technical summary and product information.

The LM393N from STMicroelectronics is a low-power dual voltage comparator IC. It is designed to operate from a wide single-supply voltage range of 2V to 36V, or from split power supplies of ±1V to ±18V. This comparator features very low supply current (0.45 mA) that is independent of the supply voltage, making it suitable for power-sensitive applications.

 

Key electrical characteristics include a low input bias current of 20 nA typical, a low input offset current of ±3 nA typical, and a low input offset voltage of ±1 mV typical. The input common-mode voltage range includes ground, and the output saturation voltage is low at 80 mV typical when sinking 4mA. The differential input voltage range is equal to the supply voltage.

 

This device is available in an 8-DIP (Plastic package) with through-hole mounting. The output types are compatible with CMOS, DTL, ECL, MOS, and TTL logic families. The LM393N is ideal for various general-purpose comparison tasks in electronic circuits.
