      Ultralow Power Quad
      Comparators with Reference
      TheLTC1443/LTC1444/LTC1445areultralowpowerquad
      comparators with a built-in reference. The comparators
      feature less than 8.5A supply current over temperature,
      an internal reference (1.182V ±1% for LTC1443 or 1.221V
      ±1% for LTC1444/LTC1445), programmable hysteresis
      (LTC1444/LTC1445) and TTL/CMOS output (LTC1443/
      LTC1445) that sinks and sources current (open-drain
      output for LTC1444). The reference output can drive a
      bypass capacitor of up to 0.01F without oscillation.
      The comparators operate from a single 2V to 11V supply
      or a dual ±1V to ±5.5V supply (LTC1443). Comparator
      hysteresis is easily programmable using two resistors and
      the HYST pin (LTC1444/LTC1445). Each comparator’s
      input operates from the negative supply to within 1.3V of
      the positive supply. The LTC1443/LTC1445 comparator
      output stage can continuously source up to 40mA. By
      eliminating the cross-conducting current that normally
      happenswhenthecomparatorchangeslogicstates,power
      supply glitches are eliminated.
      The LTC1443/LTC1444/LTC1445 are available in the
      16-pin SO, PDIP and DFN packages.
