LM2901AVQDRQ1

Overview

The LM2901AVQDRQ1 is a quad differential analog comparator from Texas Instruments, designed for automotive applications. It operates on a single or dual power supply ranging from 2 V to 32 V. The device features a SOIC-14 package and delivers a typical response time of 300 ns with a maximum input offset voltage of 2 mV. It draws a typical operating supply current of 2 mA and supports output compatibility with CMOS and TTL logic families.

Feature Summary

• AEC-Q100 qualified for automotive environments with an operating temperature range of -40°C to +125°C
• Supports wide single-supply (2 V to 32 V) and dual-supply operation
• Low input offset voltage of 2 mV and low input bias current of 250 nA
• Outputs compatible with standard CMOS and TTL logic levels

Applications

• Automotive HEV/EV and powertrain systems
• Body control modules
• Industrial sensor interfaces

Procurement Notes

Verify the specific suffix QDR indicates the SOIC-14 package and tape-and-reel packaging configuration. Confirm AEC-Q100 Grade 1 qualification status matches project requirements. Ensure the AV variant specifications align with design constraints regarding offset voltage and supply voltage limits before finalizing procurement orders.

Selection Notes

Select this component when high channel density is required in a compact SOIC-14 footprint. The AV series offers lower offset voltage compared to standard variants, making it suitable for precision sensing. Verify that the 300 ns propagation delay meets the timing requirements of the target application circuit.

Part Context

This part belongs to the LM2901AV family of automotive-grade comparators. It shares functional similarities with the LM2901AVQPWRQ1 but differs in physical package type, utilizing SOIC-14 instead of TSSOP-14. Both devices serve as quad differential comparators within Texas Instruments' automotive analog portfolio.

Replacement Considerations

LM2901AVQPWRQ1 offers identical electrical performance in a TSSOP-14 package.
