LM393N - Dual Differential Comparator

Download the LM393N datasheet PDF. This datasheet also covers the LM393 variant, as both devices belong to the same dual differential comparator family and are provided as variant models within a single manufacturer datasheet.

Description

The LM2903, LM393/LM393A, LM293A consist of two independent voltage comparators designed to operate from a single power supply over a wide voltage range.

Features

  • Single Supply Operation: 2V to 36V.
  • Dual Supply Operation: 1V to 18V.
  • Allow Comparison of Voltages Near Ground Potential.
  • Low Current Drain 800A Typ.
  • Compatible with all Forms of Logic.
  • Low Input Bias Current 25nA Typ.
  • Low Input Offset Current 5nA Typ.
  • Low Offset Voltage 1mV Typ.
