Overview
The LTC1540IMS8#PBF is a nanopower comparator with an integrated reference, housed in an 8-lead plastic MSOP package. It operates on a single supply from 2V to 11V or dual supplies of ±1V to ±5.5V. The device features ultralow quiescent current of 0.68µA (max) and includes a 1.182V ±2% internal reference capable of sourcing up to 1mA. It offers TTL/CMOS compatible outputs that can source 40mA continuously without crowbar current during state transitions. Propagation delay is 60µs with 10mV overdrive.
Feature Summary
- Ultralow power consumption with built-in 1.182V reference
- TTL/CMOS compatible outputs with high drive capability
- Programmable hysteresis via external resistors
- Wide input common mode range extending to negative supply
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Oscillator circuits
Procurement Notes
Verify the specific suffix IMS8 corresponds to the 8-lead plastic MSOP package and Industrial temperature grade (-40°C to 85°C). Confirm the #PBF designation indicates lead-free finish compliance. Ensure the ordering code matches the required commercial or industrial specifications for your design environment.
Selection Notes
Select this component when ultra-low static current is critical alongside moderate speed requirements. The integrated reference simplifies designs by removing external voltage references. Consider the 40mA output drive for direct interfacing with logic gates or small loads without additional buffering stages.
Part Context
This part belongs to the LTC1540 family of nanopower comparators. It is pin-compatible with the LTC1440 and MAX921/MAX931 devices, facilitating direct upgrades or replacements in existing designs requiring similar form factors and functionality within the Analog Devices portfolio.

FAQ
Can the reference output drive capacitive loads?
Yes, the reference output can drive a bypass capacitor of up to 0.01µF directly without oscillation. Larger capacitance values require a series damping resistor.
What is the maximum hysteresis voltage band?
The maximum voltage allowed between the REF and HYST pins is 50mV, which produces a maximum hysteresis voltage band of 100mV.
