Overview
The LTC1540IS8#TRPBF is a nanopower comparator with an integrated reference, manufactured by Analog Devices Inc. It operates within a supply voltage range of 2V to 11V and features a typical quiescent current of 0.3µA. The device includes a built-in 1.182V ± 2% reference capable of sourcing up to 1mA. Key electrical parameters include a propagation delay of 60µs at 10mV overdrive, an input offset voltage of ±12mV, and TTL/CMOS compatible outputs that can source up to 40mA continuously. It is housed in an 8-lead Plastic SO package.
Feature Summary
- Ultralow quiescent current consumption for battery-powered applications
- Integrated 1.182V reference output capable of driving bypass capacitors
- Programmable hysteresis via external resistors connected to the HYST pin
- Glitch-free CMOS output stage eliminating crowbar switching currents
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Oscillator circuits
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the 'I' grade designation corresponds to the -40°C to +85°C industrial temperature range required for your application environment. Ensure the 8-lead SOIC footprint matches your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring minimal static power draw while maintaining precise threshold detection. The wide supply range supports both single and split supply configurations. Consider the internal reference accuracy and programmable hysteresis capabilities if external components for biasing or noise immunity are to be minimized.
Part Context
This part belongs to the LTC1540 series of nanopower comparators. It is pin-compatible with devices such as the LTC1440, MAX921, and MAX931, facilitating direct upgrades or replacements in existing designs. The series offers various package options including DFN, MSOP, and SO packages to suit different space and thermal requirements.
Replacement Considerations
The datasheet explicitly lists the LTC1440, MAX921, and MAX931 as pin-compatible alternatives. Verify functional equivalence regarding reference voltage and output drive characteristics when substituting.
