LTC1440/LTC1441/LTC1442 Ultralow Power Single/Dual Comparator with Reference FEATURES DESCRIPTION Ultralow Quiescent Current: 2.1µA Typ (LTC1440) The LTC®1440/LTC1441/LTC1442 are ultralow power Wide Supply Range: single and dual comparators with built-in references. The Single: 2V to 11V comparators feature less than 3.7µA supply current over Dual: ±1V to ±5.5V temperature (LTC1440), a 1.182V ±1% reference, pro- Input Voltage Range Includes the Negative Supply grammable hysteresis (LTC1440/LTC1442) and TTL/CMOS Reference Output Drives 0.01µF Capacitor outputs that sink and source current. The reference output Adjustable Hysteresis (LTC1440/LTC1442) can drive a bypass capacitor of up to 0.01µF without TTL/CMOS Compatible Outputs oscillation. 12µs Propagation Delay with 10mV Over
