TL331EDBVRQ1

Comparators Overview

The TL331EDBVRQ1 is an automotive-grade single differential comparator from Texas Instruments, designed for high-efficiency voltage comparison. It operates within a supply voltage range of 2 V to 36 V and features a low quiescent current of 700 uA. The device offers a propagation delay of 1000 ns and supports CMOS/TTL outputs. Key electrical specifications include an input offset voltage of 2.5 mV, input bias current of 25 nA, and input offset current of 10 nA. It functions reliably across a temperature range of -40°C to +125°C and is housed in a SOT-23-5 package.

Comparators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• Single-channel differential input configuration for precise signal comparison
• Wide operating supply voltage range supporting diverse system architectures

Comparators Applications

• Automotive sensor signal conditioning
• Voltage monitoring circuits in vehicle electronics

Comparators Procurement Notes

Verify the specific suffix 'E' against official Texas Instruments documentation to confirm exact performance grades and marking codes. Ensure the component matches the required AEC-Q100 qualification level for your automotive application. Cross-reference the SOT-23-5 package dimensions with your PCB footprint design. Confirm that the output type aligns with your downstream logic requirements before finalizing procurement.

Comparators Selection Notes

Select this component when automotive reliability and wide voltage operation are critical. The TL331EDBVRQ1 is suitable for applications requiring differential inputs and robust performance under varying thermal conditions. Consider its 700 uA quiescent current if power efficiency is a secondary concern compared to voltage range. Verify compatibility with your system's output logic levels given its CMOS/TTL output capability.

Comparators Part Context

This part belongs to the TL331 series of single differential comparators manufactured by Texas Instruments. The 'Q1' suffix indicates automotive grade qualification, while 'DBVR' specifies the SOT-23-5 surface-mount package. It is distinct from non-automotive variants like the TL331IDBVR, which lack the rigorous automotive testing and qualification processes required for vehicle integration.

Comparators Replacement Considerations

Direct substitutes may include other AEC-Q100 qualified single differential comparators from Texas Instruments, such as the TL331QDBVRQ1 or TL331BQDBVRQ1, provided their electrical parameters meet the specific design requirements.
