LM2901AVQDR

Overview

The LM2901AVQDR is a quad differential analog comparator manufactured by Texas Instruments, designed for automotive applications. It features four independent channels housed in a 14-pin SOIC package. The device operates on a supply voltage ranging from 2 V to 32 V with a typical quiescent current of 2 mA. Key electrical specifications include a maximum input offset voltage of 2 mV and an input bias current of 250 nA. It supports CMOS and TTL output logic levels and has a response time of 300 ns. The component is qualified under AEC-Q100 standards and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Quad differential architecture providing four independent comparison channels
• Low power consumption with a typical operating current of 2 mA
• High precision performance characterized by a maximum input offset voltage of 2 mV

Applications

• Automotive sensor signal conditioning
• Battery management system monitoring
• Industrial control circuit protection
• Voltage threshold detection in vehicle electronics

Procurement Notes

Verify the specific suffix QD against official Texas Instruments documentation to confirm the SOIC-14 package type and tape-and-reel packaging configuration. Ensure the part number matches the exact automotive grade requirements and check for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when high accuracy is required due to its low 2 mV offset voltage specification. The wide 2 V to 32 V supply range allows flexibility in various power architectures. Consider the 300 ns propagation delay for timing-sensitive applications and ensure the thermal performance of the SOIC-14 package meets the system's heat dissipation needs within the specified -40°C to +125°C operating range.

Part Context

This device belongs to the LM2901AV series, which represents a family of precision comparators optimized for automotive environments. Unlike standard commercial variants, the AV series emphasizes reliability and stability under harsh conditions. The quad configuration integrates four comparators into a single compact package, reducing board space compared to using individual single-channel units.

Replacement Considerations

LM2901AVQDRG4Q1 is a verified alternative offering identical functionality in a different package variant.
