Application Scenarios & Design Considerations

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

Alternative Part Number

  • LTC1444CS#PBF --: Quad micropower comparator with internal reference in SO-16, functionally similar to the MAX984 quad comparator with reference; pin-compatible family from Linear Technology.
  • TLV3404IPW --: Quad nanopower comparator with reference in TSSOP-16, low supply current and wide supply range, suitable replacement for battery-powered comparator applications.
  • LM339AMX --: Industry-standard quad comparator in SO-14, widely available and low cost; lacks internal reference so external reference is required, but electrically compatible for basic comparator use.
  • TLV3404IDR --: Quad nanopower comparator with reference, low supply current, suitable drop-in replacement for battery-powered MAX984 applications.
  • LMV344MA/NOPB --: Quad low-voltage comparator in SO-14/16 family, wide availability and similar supply range, usable as an alternative with minor layout checks.
