LM4128BMFX-2.0/NOPB

Voltage Reference Overview

The LM4128BMFX-2.0/NOPB is a precision micropower series voltage reference manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides a fixed output voltage of 2.048 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. It supports a maximum input voltage of 6 V and exhibits a temperature coefficient of 75 ppm/°C.

Voltage Reference Feature Summary

Provides stable reference voltage with high initial accuracy
Operates at low quiescent current for power efficiency
Designed for compact surface-mount applications

Voltage Reference Applications

Portable instrumentation requiring precise voltage references
Battery-powered measurement systems
Data acquisition channels

Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB and packaging options like reel or cut tape. Confirm that the specific variant matches the required output voltage and accuracy grade. Ensure compatibility with the intended operating temperature range and supply voltage constraints before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a fixed 2.048 V reference is needed in a small footprint. Consider the 0.2% initial accuracy and 75 ppm/°C temperature coefficient against application requirements. Evaluate the 20 mA maximum shunt current capability to ensure it meets load demands without exceeding thermal limits.

Voltage Reference Part Context

This component belongs to the LM4128 family of precision micropower series voltage references from Texas Instruments. The family offers various output voltages and accuracy grades packaged in SOT-23 form factors. These devices are designed for applications requiring stable reference voltages with minimal power consumption.

Voltage Reference Replacement Considerations

LM4128AMFX-2.0/NOPB offers higher accuracy (0.1%) but similar electrical characteristics. LM4128DMFX-2.0/NOPB provides lower cost with reduced accuracy (1%). Automotive-grade alternatives include the LM4128BQ1MF-2.0/NOPB series.
