LM2901QT14-13

Overview

The LM2901QT14-13 is an automotive-compliant quad differential comparator manufactured by Diodes Incorporated. It features four independent precision voltage comparators with very low input offset voltage specifications, designed for operation from single power supplies ranging from 2V to 36V or split supplies of ±1V to ±18V. The device offers low supply current drain independent of the supply voltage magnitude and provides output voltage compatibility with TTL, MOS, and CMOS logic families. Qualified to AEC-Q100 Grade 1 standards, it supports automotive applications requiring specific change control and PPAP submission.

Feature Summary

• Automotive compliance with AEC-Q100 Grade 1 qualification and PPAP capability
• Very low input offset voltage specification for high precision applications
• Wide power supply range supporting both single and dual supply configurations
• Output voltage compatible with standard TTL, MOS, and CMOS logic levels

Applications

• Motor control systems in automotive environments
• Production process automation industrial designs
• Voltage monitoring circuits requiring ground sense capability
• Signal conditioning interfaces between analog sensors and digital logic

Procurement Notes

Verify that the component matches the specified TSSOP-14 package code (T14) and the -13 tape and reel packing quantity of 2,500 units. Confirm the suffix indicates the standard non-A grade variant rather than the low offset voltage A-grade version. Ensure the procurement channel sources parts directly from authorized distributors to maintain AEC-Q100 certification validity and traceability required for automotive assembly processes.

Selection Notes

Select this component when designing circuits that require multiple independent comparators within a single integrated circuit footprint. The quad configuration reduces board space compared to using individual dual devices. Consider the low input bias current and wide common-mode input voltage range that includes ground, which simplifies interface design for various sensor types without requiring complex level shifting networks.

Part Context

This part belongs to the LM2901Q/LM2901AQ series of automotive compliant dual and quad differential comparators produced by Diodes Incorporated. The series is engineered to operate over an extended temperature range suitable for harsh automotive environments. It shares functional similarities with other industry-standard comparators but distinguishes itself through its specific AEC-Q100 qualification and manufacturing in IATF16949 certified facilities.

Replacement Considerations

LM2901AQT14-13: Offers lower typical input offset voltage (1mV vs 2mV) while maintaining identical pinout and electrical characteristics.
