LM393N Description

Short technical summary and product information.

The LM393N from SE is a dual voltage comparator IC designed for versatile power supply operation, accepting single supplies from 2V to 36V or dual supplies from ±1V to ±18V. Its key features include very low supply current (0.45 mA) that is independent of the supply voltage, and a low input bias current of 20 nA typical. The input common-mode voltage range includes ground, even when operated from a single supply.

 

This comparator boasts a low input offset voltage of ±1 mV typical and a low output saturation voltage of 80 mV typical when sinking 4mA. The differential input voltage range is equal to the supply voltage, and its outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic levels. The LM393N is available in an SO-8 package, suitable for surface mount applications.

 

Operating temperature ranges vary by specific part designation, with options from -55°C to +125°C for LM193 variants, -40°C to +105°C for LM293 variants, and 0°C to +70°C for LM393 variants. Thermal resistance data is provided for various package types, including SO-8, TSSOP8, DIP8, MiniSO-8, and DFN8 2x2mm.
