SNOS977F – MAY 2001 – REVISED MAY 2016 LM397 Single General-Purpose Voltage Comparator
1 Features 3 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. 1 TA = 25В°C. Typical Values Unless Otherwise
Specified.
5-Pin SOT-23 Package
Industrial Operating Range -40В°C to +85В°C
Single or Dual Power Supplies
Wide Supply Voltage Range 5 V to 30 V
Low Supply Current 300 ВµA
Low Input Bias Current 7 nA
Low Input Offset Current В±1 nA
Low Input Offset Voltage В±2 mV
Response Time 440 ns (50-mV Overdrive) …
