Overview
The LMX331HAXK+T is a single-channel, low-voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.8V to 5.5V and supports an automotive temperature range from -40°C to +125°C. The device features internal hysteresis of 2mV for noise immunity and utilizes a 5-pin SC70 package measuring 2.0mm x 2.1mm x 1.0mm. At VDD = 5.0V, the typical supply current is 60µA per comparator.
Feature Summary
- Integrated 2mV internal hysteresis prevents output oscillations caused by noise or slow-moving input signals.
- Drop-in pin-for-pin compatible replacement for LMV331/LMV393/LMV339 series comparators.
- Operates over an extended automotive temperature range (-40°C to +125°C) with wide supply voltage support.
- Small space-saving SC70 package design suitable for portable and battery-powered electronics.
Applications
- Mobile Communications
- Automotive Applications
- Battery-Powered Electronics
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status indicated by the '+' suffix in the ordering code. Ensure the SC70 package variant matches the specific footprint requirements of the target PCB layout. Review absolute maximum ratings to prevent damage during soldering or operation.
Selection Notes
Select this component when noise immunity is critical due to its built-in hysteresis feature. Consider it for designs requiring direct replacement of standard LMV331 devices without schematic changes. Evaluate the SC70 package dimensions against available board space constraints. Verify that the open-drain output configuration aligns with the pull-up resistor requirements of the downstream circuitry.
Part Context
This part belongs to the LMX331/LMX393/LMX339 family of general-purpose, low-voltage comparators. Manufactured using advanced submicron CMOS technology, the series offers superior performance compared to traditional BiCMOS or bipolar versions. The 'H' designation specifically denotes the inclusion of internal hysteresis, distinguishing it from the standard LMX331 variant.

FAQ
What is the function of the 'H' suffix in the LMX331H model?
The 'H' suffix indicates that the device includes 2mV of internal hysteresis, which provides noise immunity and prevents output oscillations during slow-moving input signal transitions.
How does the LMX331H compare to the standard LMX331?
The LMX331H is a drop-in, pin-for-pin compatible replacement for the standard LMX331 but adds internal hysteresis for improved noise immunity while maintaining similar electrical characteristics.
