LM2901VQDR

Overview

The LM2901VQDR is a quad differential analog comparator manufactured by Texas Instruments. It features CMOS and TTL compatible outputs within an SOIC-14 package. The device operates on a supply voltage ranging from 2 V to 32 V with a typical operating current of 2.5 mA. Key electrical specifications include a response time of 300 ns, an input offset voltage (Vos) of 7 mV, and an input bias current (Ib) of 250 nA. The component supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Quad differential architecture providing four independent comparison channels in a single package
• CMOS and TTL output compatibility for versatile logic interfacing
• Wide single-supply voltage operation capability up to 32 V

Applications

• General purpose analog signal comparison circuits
• Voltage monitoring systems requiring multiple thresholds
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'QDR' corresponds to the SOIC-14 surface mount package and reel/cut tape availability. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout design.

Selection Notes

Select this component when multiple differential comparisons are required within space-constrained designs. The SOIC-14 package offers a balance between channel density and thermal performance. Consider the 300 ns response time against application speed requirements. Verify that the 7 mV input offset voltage meets the precision needs of the specific sensing circuitry involved.

Part Context

This device belongs to the LM2901V series of analog comparators. It serves as a high-density alternative to discrete comparator solutions. The quad configuration reduces board space compared to using individual dual or single comparators. It is designed for general-purpose applications where moderate speed and wide voltage tolerance are prioritized.

Replacement Considerations

Check for LM2901VQDRG4 as a potential lead-free variant within the same family. Verify pin compatibility before substituting with other quad comparators from different manufacturers.
