Overview
The LM211QDREP is a single-channel differential analog comparator manufactured by 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 an open collector and emitter output capable of sourcing up to 50 mA per channel. The device exhibits a typical response time of 165 ns, with a maximum input offset voltage of 3 mV and an input bias current of 100 nA. 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
- High-speed differential comparison with 165 ns response time
- Versatile open collector and emitter output configuration
- Extended industrial temperature operation capability
Applications
- Automotive sensor signal conditioning
- Voltage threshold detection circuits
- Over-voltage protection systems
- Pulse width modulation generation
Procurement Notes
Verify the specific suffix 'REP' against official Texas Instruments documentation to confirm it denotes a Mil-enhanced or specific tape-and-reel variant distinct from standard commercial grades. Ensure the ordering part number matches the exact package and qualification requirements for your design. Cross-reference the manufacturer's latest datasheet revision history to validate component availability and any potential assembly or material updates that may affect integration.
Selection Notes
Select this component when automotive qualification and high-speed differential comparison are required. The open collector/emitter output allows flexible interfacing with various logic families. Consider the 50 mA output drive capability for direct load driving. Verify that the 3.5 V minimum supply voltage aligns with the system power rails. The SOIC-8 package offers a compact footprint suitable for space-constrained automotive PCB layouts.
Part Context
This device belongs to the LM211 series of precision comparators. The 'Q1' designation typically indicates automotive qualification, while the 'REP' suffix suggests a specific manufacturing or packaging variation. It serves as a robust alternative to general-purpose comparators in environments requiring high reliability and wide operating voltage ranges. The series is known for its compatibility with TTL and DTL logic levels.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official replacement guide or contact technical support for verified cross-reference information before substituting this component.
