- **ESD Protection:** ±15kV (Human Body Model)  

The MAX971CSA is commonly used in audio amplification, signal conditioning, active filters, and precision instrumentation applications.  

(Note: Always verify datasheet details for the latest specifications.)

Application Scenarios & Design Considerations

Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators

Alternative Part Number

  • LT1017CS8 --: Comparable micropower comparator with similar supply voltage range and open-drain output, suitable drop-in for many MAX971 applications.
  • TLV3011IDBVR --: Low-power comparator with integrated reference, similar function and small package, good alternative when board space is limited.
  • LM393DR --: Widely available dual comparator with similar electrical characteristics; can replace MAX971 in less critical designs with minor pinout adaptation.
