LMV762QMA/NOPB

Overview

The LMV762QMA/NOPB is a dual-channel precision analog comparator manufactured by Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It operates within a supply voltage range of 2.7 V to 5 V and consumes 700 uA of operating current. The device features a push-pull output capable of sourcing or sinking 60 mA per channel. Key electrical specifications include a maximum input offset voltage (Vos) of 1 mV, an input bias current (Ib) of 5 pA, and a common-mode voltage (Vcm) extending down to -300 mV. The response time is specified at 120 ns, and it functions reliably across a temperature range of -40°C to +125°C in an SOIC-8 package.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards for robust performance in vehicle environments.
• Precision comparison capability with low input offset voltage ensuring accurate signal threshold detection.
• High drive strength output stage providing substantial current capacity for direct load interfacing.

Applications

• Automotive sensor signal conditioning
• Battery management system monitoring
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'MA' corresponds to the SOIC-8 tube packaging configuration when ordering. Confirm that the AEC-Q100 qualification aligns with your target automotive application requirements. Ensure the supply voltage constraints between 2.7 V and 5 V are strictly maintained during design integration to guarantee proper comparator operation and longevity.

Selection Notes

Select this component when high precision and automotive durability are required for low-voltage single-supply systems. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-collector alternatives. Consider the 120 ns response time against your system's speed requirements to ensure adequate switching performance without unnecessary latency.

Part Context

This part belongs to the LMV762Q family of low-voltage precision comparators from Texas Instruments. It shares functional similarities with other members like the LMV762MMX/NOPB but differs in packaging and reel specifications. The Q-series designation specifically indicates its suitability for qualified automotive electronics, distinguishing it from standard commercial grade variants.

Replacement Considerations

The LMV762MMX/NOPB serves as a functional alternative within the same family, offering similar electrical characteristics but in a VSSOP-8 tape-and-reel package. Verify pinout compatibility and thermal performance differences before substitution. Other non-automotive grade comparers may lack the necessary qualification for automotive deployment despite matching electrical specs.
