Overview
The LM2901QDRQ1 is a quad differential analog comparator from Texas Instruments, designed for automotive applications. It features four independent comparators in a SOIC-14 package. The device operates with a supply voltage range of 5 V to 30 V and consumes 2.5 mA of quiescent current. Key electrical specifications include a maximum input offset voltage of 7 mV and an input bias current of 250 nA. The propagation delay is specified at 300 ns. It supports CMOS and TTL output types and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- Quad differential configuration providing four independent comparison channels
- CMOS and TTL compatible output interface
Applications
- Automotive electronic systems requiring signal comparison
- Voltage monitoring circuits in vehicle electronics
- Threshold detection in automotive sensor interfaces
Procurement Notes
Verify the specific suffix QDRQ1 against the manufacturer's official datasheet to confirm the exact package variant and automotive grade designation. Ensure the ordering part number matches the required SOIC-14 footprint and lead frame finish. Cross-reference the revision level with the latest product data sheet to avoid discrepancies in pinout or electrical characteristics during procurement.
Selection Notes
Select this component when automotive reliability and quad-channel integration are required. The 300 ns response time suits general-purpose comparisons rather than high-speed applications. Verify that the 5 V minimum supply voltage aligns with the system power rails. Consider the SOIC-14 package dimensions for PCB layout constraints compared to TSSOP alternatives.
Part Context
This device belongs to the LM2901 family of quad comparators. The 'Q' prefix indicates automotive qualification, while 'RQ1' specifies the reel packaging and RoHS compliance status. It serves as a specialized version of the standard LM2901, tailored for harsh automotive environments with extended temperature capabilities and rigorous quality standards.
Replacement Considerations
LM2901QDRG4Q1 is a documented alternative within the same automotive series.
