Overview
The LM2901VQDRG4Q1 is a quad differential comparator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It features four independent channels in a 14-pin SOIC package. The device operates on a single supply voltage ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. Key electrical parameters include a maximum input offset voltage of 7 mV at 5 V and a typical propagation delay of 300 ns. The quiescent current is typically 2.5 mA, and the output stage supports CMOS and TTL logic levels.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- Quad differential architecture providing four independent comparison channels
- Wide single-supply operating range extending up to 36 V
- High-speed response capability with 300 ns typical propagation delay
Applications
- Automotive sensor signal conditioning
- Voltage level detection circuits
- Window comparator configurations
- Over-voltage protection systems
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status. Confirm the Q1 designation aligns with required automotive qualification standards. Ensure the DRG4 package variant matches the target PCB footprint requirements. Validate that the voltage ratings meet the specific application's operational limits before procurement.
Selection Notes
Select this component when high-speed differential comparison is required in automotive environments. The wide supply voltage range accommodates various system architectures. Consider the 7 mV offset voltage specification for precision applications. The open-collector output requires appropriate pull-up resistor selection for desired logic levels.
Part Context
This part belongs to the LM2901-Q1 family of automotive quad comparators. It shares functional similarities with other members like LM2901AVQPWRG4Q1 but differs in package type and specific performance metrics. The series is designed to replace older discrete solutions with integrated multi-channel functionality.
Replacement Considerations
LM2901VQDR is the non-automotive grade equivalent. LM2901AVQPWRG4Q1 offers faster response times in a TSSOP package. NCV2901DTBR2G is an alternative from onsemi with similar specifications.
