LM211QDRRB

Overview

The LM211QDRRB is a single-channel differential comparator from Texas Instruments, housed in an SOIC-8 surface-mount package. It operates on a supply voltage range of 3.5 V to 30 V or ±1.75 V to ±15 V. Key electrical parameters include a maximum response time of 165 ns and a maximum input offset voltage of 3 mV at ±15 V. The device features open collector and emitter outputs capable of sourcing up to 50 mA per channel. It supports strobe functionality and maintains low input bias current characteristics suitable for precision analog signal processing applications.

Feature Summary

• Differential input configuration with integrated strobe capability for precise timing control
• Open collector and emitter output structure supporting high current drive capabilities
• Wide single or dual power supply operation range for flexible system integration

Applications

• Medical devices requiring precise signal comparison
• Industrial control systems utilizing differential sensing
• General-purpose analog comparator circuits

Procurement Notes

Verify the specific suffix RB against official Texas Instruments documentation to confirm exact manufacturing lot details and revision status. Ensure the SOIC-8 footprint matches your PCB design constraints. Cross-reference the AEC-Q100 qualification if automotive reliability is required, as standard LM211 variants may differ. Confirm that the strobe pinout aligns with your timing requirements before finalizing procurement orders.

Selection Notes

Select this component when a single differential comparator with strobe functionality is required. Consider the 165 ns response time and 3 mV offset voltage for accuracy needs. Evaluate the 50 mA output current capability against load requirements. Compare against standard LM211 variants if automotive qualification or specific packaging revisions are not necessary for the application.

Part Context

This part belongs to the LM211 series of differential comparators manufactured by Texas Instruments. It shares architectural similarities with other members like the LM211DR but includes specific suffix designations indicating particular manufacturing revisions or packaging configurations. The series is known for fast response times and versatile output structures.
