Comparators

ComparatorHigh-SpeedVoltage Comparator

The LM311PSR is a versatile, high-speed single voltage comparator from Texas Instruments, widely used in industrial and consumer applications for its ability to interface with TTL/MOS logic and drive high-voltage loads.

Best for

  • Level shifting
  • Zero-crossing detection
  • Relay/Lamp driving

Avoid if

  • Extremely low power applications (higher bias current than modern CMOS comparators)

Check before use

  • Pull-up resistor value for output logic levels
  • Strobe pin configuration
