LM397 - Single General-Purpose Voltage Comparator

General Description

The LM397 device is a single voltage comparator with an input common mode that includes ground.

The LM397 is designed to operate from a single 5-V to 30-V power supply or a split power supply.

Its low supply current is virtually independent of the magnitude of the supply voltage.

Key Features

  • 1 TA = 25°C. Typical Values Unless Otherwise Specified.
  • 5-Pin SOT-23 Package.
  • Industrial Operating Range.
  • 40°C to +85°C.
  • Single or Dual Power Supplies.
  • Wide Supply Voltage Range 5 V to 30 V.
  • Low Supply Current 300 µA.
  • Low Input Bias Current 7 nA.
  • Low Input Offset Current ±1 nA.
  • Low Input Offset Voltage ±2 mV.
  • Response Time 440 ns (50-mV Overdrive).
  • Input Common-Mode Voltage 0 to VS.
