LM397 Description
LM397 Single General Purpose Voltage Comparator August 2006 LM397 Single General Purpose Voltage Comparator General .
The LM397 is a single voltage comparator with an input common mode that includes ground.
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 5-Pin SOT23 package
LM397 Applications
* n n n n A/D converters Pulse, square wave generators Peak detector Industrial applications
