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 APPLICATIONS • A/D Converters • Pulse, Square Wave Generators • Peak Detector • Industrial Applications Typical Circuit Connection Diagram Top View Figure 1. 5-Pin SOT-23 Package See Package Number DBV0005A Figure 2. Inverting Comparator with Hysteresis 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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
