LM4128BMF-1.8/NOPB

Voltage Reference Overview

The LM4128BMF-1.8/NOPB is a precision micropower series voltage reference manufactured by Texas Instruments, housed in a compact SOT-23-5 surface-mount package. It delivers a fixed output voltage of 1.8 V with an initial accuracy of 0.2%. The device operates within a temperature range of -40°C to +125°C and features a maximum shunt current of 20 mA. Key electrical specifications include a maximum input voltage of 6 V and a typical operating supply current of 60 µA.

Voltage Reference Feature Summary

• Provides stable reference voltage with high initial accuracy
• Designed for low power consumption applications
• Compact footprint suitable for space-constrained designs

Voltage Reference Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring precise analog references
• Microcontroller peripheral voltage regulation

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the 'M' suffix corresponds to the SOT-23-5 package variant. Ensure the '-1.8' designation matches the required 1.8 V output level for your circuit design before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 1.8 V reference is required with 0.2% initial accuracy. It is suitable for applications needing low quiescent current around 60 µA. Consider the 6 V maximum input voltage limit and 20 mA shunt current capability during circuit planning.

Voltage Reference Part Context

This part belongs to the LM4128 family of precision micropower series voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades, all sharing similar low-power characteristics and compact SOT-23 packaging options for general-purpose voltage referencing tasks.

Voltage Reference Replacement Considerations

Check for LM4128BMF-1.8 without NOPB if lead-free compliance is not required. Verify compatibility with other LM4128 variants offering different accuracies or output voltages within the same package.
