The LTC1540IS8#TR is a nanopower comparator manufactured by LT, featuring an integrated reference. This single comparator is designed for ultralow power consumption, with a typical quiescent current of 0.3µA and a maximum of 0.6µA over the commercial temperature range.
Key electrical specifications include a wide supply voltage range from 2V to 11V single supply or ±1V to ±5.5V dual supply. It incorporates a 1.182V ±2% reference output capable of driving a 0.01µF capacitor without oscillation. The comparator offers programmable hysteresis and TTL/CMOS compatible outputs that can sink and source current up to 40mA continuously. Its input voltage range extends from the negative supply up to within 1.3V of the positive supply.
The LTC1540IS8#TR is available in 8-pin SO, MSOP, and 3mm x 3mm DFN packages, making it suitable for space-limited applications. Its design eliminates cross-conducting current, preventing power supply glitches during logic state changes. Applications include battery-powered system monitoring, threshold detection, window comparators, and oscillator circuits.
The LTC1540IS8#TR operates from a single 2V to 11V supply or a dual ±1V to ±5.5V supply.
