LM397  
Single General Purpose Voltage Comparator  
General Description  
Features  
The LM397 is a single voltage comparator with an input  
common mode that includes ground. The LM397 is designed  
to operate from a single 5V to 30V power supply or a split  
power supply. Its low supply current is virtually independent  
of the magnitude of the supply voltage.  
(TA = 25˚C. Typical values unless otherwise specified).  
n SOT23-5 package  
n Industrial operating range  
n Single or dual power supplies  
n Wide supply voltage range  
n Low supply current  
n Low input bias current  
n Low input offset current  
n Low input offset voltage  
n Response time  
−40˚C to +85˚C  
5V to 30V  
300µA  
7nA  
The LM397 features an open collector output stage. This  
allows the connection of an external resistor at the output.  
The output can directly interface with TTL, CMOS and other  
logic levels, by tying the resistor to different voltage levels  
(level translator).

The LM397 is available in space saving SOT23-5 package  
and pin compatible to TI’s TL331, single differential com-  
parator.
