LM4132EMF-4.1/NOPB

Voltage Reference Overview

The LM4132EMF-4.1/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a compact SOT-23-5 surface-mount package. It provides a fixed nominal output voltage of 4.096 V with an initial accuracy tolerance of ±0.5%. The device operates within an input voltage range of 4.5 V to 6 V and supports a maximum shunt current of 20 mA. Key electrical characteristics include a temperature coefficient of 30 ppm/°C and a typical supply current of 60 µA. It functions reliably across an extended industrial temperature range from -40°C to +125°C.

Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB and reel specifications against official Texas Instruments documentation. Confirm RoHS compliance status and ensure the ordering code matches the required packaging format. Cross-reference datasheet revisions to validate pinout and electrical parameters before final procurement decisions.

Voltage Reference Selection Notes

Select this component when a 4.096 V reference with ±0.5% accuracy is required in a small footprint. Ensure the input voltage remains within the specified 4.5 V to 6 V window. Consider the 30 ppm/°C drift rate for thermal stability needs. Verify that the 20 mA load current capability meets system demands without exceeding thermal limits.
