FEATURES
DESCRIPTION
The LM397 is a single voltage comparator with an
2
(TA = 25°C. Typical Values Unless Otherwise
input common mode that includes ground. The
Specified).
LM397 is designed to operate from a single 5V to
5-Pin SOT-23 Package
30V power supply or a split power supply. Its low
Industrial Operating Range
−40°C to +85°C
supply
current
is
virtually
independent
of
the
magnitude of the supply voltage.
Single or Dual Power Supplies
The LM397 features an open collector output stage.
Wide Supply Voltage Range 5V to 30V
This allows the connection of an external resistor at
Low Supply Current 300µA
the output. The output can directly interface with TTL,
Low Input Bias Current 7nA
CMOS and other logic levels, by tying the resistor to
Low Input Offset Current ±1nA
different voltage levels (level translator).
Low Input Offset Voltage ±2mV
The LM397 is available in space saving 5-Pin SOT-
23 package and pin compatible to TI’s TL331, single
Response Time 440ns (50mV Overdrive)
differential comparator.
Input Common Mode Voltage 0 to VS - 1.5V

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
