1 / 9 page  LM397 Single General Purpose Voltage Comparator General Description 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. 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. Features (T A = 25˚C. Typical values unless otherwise specified). n SOT23-5 package n Industrial operating range −40˚C to +85˚C n Single or dual power supplies n Wide supply voltage range 5V to 30V n Low supply current 300µA n Low input bias current 7nA n Low input offset current ±1nA n Low input offset voltage ±2mV n Response time 440ns (50mV overdrive) n Input common mode voltage 0 to V S - 1.5V Applications n A/D converters n Pulse, square wave generators n Peak detector n Industrial applications Connection Diagram SOT23-5 20022108 Top View Typical Circuit Ordering Information Package Part Number Package Marking Transport Media NSC Drawing 5-Pin SOT-23 LM397MF C397 1k Units Tape and Reel MF05A LM397MFX 3k Units Tape and Reel 20022109 FIGURE 1.
