Overview
The LM211QDRG4Q1 is a single-channel differential comparator from Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It operates within a supply voltage range of 3.5 V to 30 V and features open collector and open emitter outputs capable of sourcing up to 50 mA per channel. The device exhibits a typical response time of 165 ns and an input offset voltage of 3 mV. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in an SOIC-8 surface-mount package.
Feature Summary
- Automotive-grade reliability certified to AEC-Q100 standards
- Dual-output architecture providing both open collector and open emitter configurations
- Integrated strobe functionality for precise signal gating
Applications
- Automotive electronic control units
- Industrial sensor interface circuits
- Voltage threshold detection systems
Procurement Notes
Verify the complete part number including the G4 suffix to confirm RoHS compliance and specific packaging configuration. Confirm that the SOIC-8 package variant matches the intended PCB footprint requirements. Ensure the AEC-Q100 qualification aligns with the target automotive application's reliability specifications before finalizing procurement.
Selection Notes
Select this component when a single differential comparator with dual output types is required for automotive environments. The wide supply voltage range supports various system architectures. Consider the 165 ns response time against application speed requirements. Verify thermal management needs for operation at maximum ambient temperatures within the specified range.
Part Context
This device belongs to the LM211 family of differential comparators manufactured by Texas Instruments. The Q1 designation indicates automotive qualification, while the G4 suffix typically denotes lead-free and RoHS-compliant construction. It serves as a specialized version of the standard LM211 comparator tailored for high-reliability automotive electronics.
Replacement Considerations
The LM211QDRQ1 is a direct functional substitute within the same family. Verify pin compatibility and electrical parameter alignment before substitution.
