LM4040QCEM3-3.0/NOPB

Overview

The LM4040QCEM3-3.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for automotive applications. It provides a fixed output voltage of 3.0 V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +125°C and features a maximum noise of 35 µVrms from 10 Hz to 10 kHz. It requires a minimum cathode current of 70 µA and supports a maximum cathode current of 15 mA. The component is housed in a SOT-23 package.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Micropower operation suitable for battery-powered systems
Low-noise performance for precision analog circuits

Applications

Automotive sensor signal conditioning
Battery management systems
Precision data acquisition modules

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification and 'CEM3' denotes the SOT-23 package variant. Confirm RoHS compliance status via the official datasheet. Ensure the operating temperature range meets the target application's environmental requirements before procurement.

Selection Notes

Select this component when automotive reliability is required alongside low power consumption. Compare against standard industrial grades if temperature extremes are not critical. Verify that the 1% accuracy meets system tolerance requirements.

Part Context

This part belongs to the LM4040-N family of micropower shunt references. It shares functional similarities with other LM4040 variants but is distinguished by its automotive qualification and extended temperature range capabilities.
