Overview
The LM211QD is a single-channel analog comparator from the LMx11 family, designed for automotive applications with AEC-Q100 qualification. It features differential inputs and open collector/emitter outputs capable of sourcing up to 50 mA. The device operates on a supply voltage range of 3.5 V to 30 V with a typical quiescent current of 6 mA. Key electrical specifications include a response time of 115 ns, an input offset voltage of 3 mV, and an input bias current of 75 nA. It functions within a temperature range of -40°C to +125°C and is housed in an SOIC-8 surface-mount package.
Feature Summary
- Automotive-grade reliability with AEC-Q100 certification
- High-speed differential comparison with strobe functionality
- Robust output stage supporting open collector and emitter configurations
- Wide operating voltage range suitable for diverse power systems
Applications
- Automotive engine control units
- Battery management systems
- Industrial motor control circuits
- Voltage monitoring and threshold detection
Procurement Notes
Verify the specific suffix 'QD' corresponds to the SOIC-8 package and standard automotive grade variant. Confirm that the AEC-Q100 qualification status meets your project's reliability requirements. Ensure the ordering quantity aligns with the manufacturer's standard packaging constraints. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component when high-speed differential comparison is required in automotive environments. The 50 mA output drive capability allows direct interfacing with various loads without additional buffering. Consider the 115 ns response time for timing-sensitive applications. The wide supply voltage range provides flexibility in system design compared to lower-voltage alternatives.
Part Context
This part belongs to the LMx11 series of differential comparators, which includes quad variants like the LM311. The 'Q' designation indicates automotive qualification, while 'D' specifies the SOIC-8 package. It serves as a specialized version of general-purpose comparators, optimized for harsh automotive conditions and higher reliability standards.
Replacement Considerations
LM211QDRG4Q1 is a verified equivalent offering identical electrical characteristics and automotive qualification. LM211QDREP is another qualified alternative within the same product family. Verify pinout compatibility and package dimensions before substitution.
