Product Overview

The LTC1540IS8#PBF is a Nanopower Comparator with a built-in voltage reference. The comparator features less than 0.6µA supply current over the commercial temperature range, a 1.182V ±2% reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. The comparator operates from a single 2 to 11V supply or a dual ±1 to ±5.5V supply. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. Each comparator's input operates from the negative supply to within 1.3V of the positive supply. The comparator output stage can continuously source up to 40mA. By eliminating the cross-conducting current that normally occur when the comparator changes logic states, power supply glitches are eliminated.
  • Ultralow quiescent current (0.3µA typical)
  • Reference output drives 0.01µF capacitor
  • Adjustable hysteresis
  • Input voltage range includes the negative supply
  • Reference output sources up to 1mA
  • TTL/CMOS compatible outputs
  • 60µs Propagation delay with 10mV overdrive
  • No crowbar current
  • 40mA Continuous source current
  • Pin compatible with LTC1440, MAX921, MAX931
