Application Scenarios & Design Considerations

Single Differential Comparator

Alternative Part Number

  • LM393DR --: Dual differential comparator in SOIC-8, widely available and pin-compatible in function; a standard drop-in choice when a single comparator in SOT-23 is not strictly required.
  • LMV331IDBVR --: Single low-voltage comparator in SOT-23-5 with similar supply range and open-drain output, making it a close functional substitute for the TL331.
  • MAX9021AXK+T --: Single comparator in SC70-5 with low supply current and open-drain output, suitable as an alternative from a different series and vendor.
