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.

(T_A= 25˚C. Typical values unless otherwise specified).

n 5-Pin SOT23 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

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 5-Pin SOT23 pack-

age and pin compatible to TI’s TL331, single differential

comparator.
