LM4128AMF-3.0

Voltage Reference Overview

The LM4128AMF-3.0 is a micropower series voltage reference manufactured by Texas Instruments, housed in a SOT-23 package. It provides a fixed output voltage of 3 V with an initial accuracy of 0.1% and a temperature coefficient of 75 PPM/C. The device supports a maximum input voltage of 6 V and a maximum shunt current of 20 mA. It operates within a temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Provides stable precision voltage reference performance
• Designed for low power consumption applications
• Capable of operation across extended industrial temperature ranges

Voltage Reference Applications

• Portable instrumentation systems
• Battery-powered measurement devices
• Data acquisition circuits requiring stable references

Voltage Reference Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct voltage and tolerance specifications. Confirm RoHS compliance status as indicated in manufacturer documentation. Check for obsolete or end-of-life status prior to procurement planning.

Voltage Reference Selection Notes

Select this component when a 3 V reference with 0.1% accuracy is required in a compact SOT-23 form factor. Ensure the application current does not exceed the 20 mA shunt limit. Consider thermal management if operating near the upper temperature boundary.

Voltage Reference Part Context

This part belongs to the LM4128 series of micropower series voltage references from Texas Instruments. It shares the same family architecture as other variants like the LM4128BMF and LM4128DMF, differing primarily in output voltage and accuracy grades.

Voltage Reference Replacement Considerations

LM4128AMF-3.0/NOPB is a documented equivalent variant within the same product line.
