LTC1841/LTC1842/LTC1843 Ultralow Power Dual Comparators with Reference FEATURES DESCRIPTION Ultralow Quiescent Current: 3.5µA Typ The LTC®1841/LTC1842/LTC1843 are ultralow power dual Open-Drain Outputs Typically Sink comparators with built-in reference (LTC1842/LTC1843). Greater Than 20mA The comparators feature less than 5.7µA supply current Wide Supply Range: (LTC1841) over temperature, a 1.182V ±1% reference, program- Single: 2V to 11V mable hysteresis and open-drain outputs that sink cur- Dual: ±1V to ±5.5V rent. The reference output can drive a bypass capacitor of Input Voltage Range Includes the Negative Supply up to 0.01µF without oscillation. Reference Output Drives 0.01µF Capacitor The LTC1841 operates from a single 2V to 11V supply or Adjustable Hysteresis a dual ±1
