Overview
The LM2901AQS14-13 is an automotive-compliant quad differential comparator from Diodes Incorporated, housed in a 14-pin SOIC package. It operates on single supplies from 2V to 36V or dual supplies of ±1.0V to ±18V. The device features very low supply current drain independent of voltage and includes four independent precision comparators with A-device specifications for minimal offset. It supports direct interfacing with TTL and CMOS logic families.
Feature Summary
- Qualified to AEC-Q100 Grade 1 standards for automotive reliability
- Features extremely low typical input offset voltage of 1mV
- Offers wide common-mode input voltage range including ground
- Provides open-collector outputs compatible with various logic families
Applications
- Automotive sensor signal conditioning
- Battery management system monitoring
- Industrial control circuit threshold detection
- High-voltage digital logic gate implementations
Procurement Notes
Verify the specific 'A' suffix indicates the low offset voltage variant during procurement. Confirm the 'Q' designation aligns with required automotive quality standards. Ensure the SO-14 package matches your PCB footprint requirements. Check RoHS compliance documentation if environmental regulations apply to your manufacturing process.
Selection Notes
Select this component when precise voltage comparison is critical in automotive environments. The low offset voltage ensures accurate switching thresholds. Verify that the open-collector output configuration fits your pull-up resistor strategy. Consider the wide supply voltage range for flexibility in power distribution networks.
Part Context
This part belongs to the LM2901Q series of precision comparators designed for robust performance in harsh environments. It shares architectural similarities with standard industrial comparators but adds automotive qualification. The quad configuration allows multiple comparisons within a single integrated circuit, reducing board space.
Replacement Considerations
LM2901QS14-13 serves as a non-low-offset alternative within the same package family.
