LM4128AMF-4.1/NOPB

Voltage Reference Overview

The LM4128AMF-4.1/NOPB is a precision shunt voltage reference manufactured by Texas Instruments, designed for surface-mount applications in the SOT-23-5 package. It provides a fixed output voltage of 4.096 V with an initial accuracy of 0.1% and a temperature coefficient of 75 ppm/°C. The device operates within a supply voltage range up to 6 V and draws a typical quiescent current of 60 µA. It supports a maximum shunt current of 20 mA and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Voltage Reference Feature Summary

Delivers high-precision voltage regulation with tight initial tolerance specifications.
Optimized for low-power consumption suitable for battery-operated systems.
Engineered for stable performance across wide industrial temperature variations.

Voltage Reference Applications

Portable instrumentation requiring precise analog references
Data acquisition systems needing stable voltage benchmarks
Battery-powered measurement devices

Voltage Reference Procurement Notes

Verify the specific suffix 'AMF' against the official datasheet to confirm the exact accuracy grade and temperature coefficient. Ensure the ordering part number matches the required package style and tape-and-reel quantity. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a 4.096 V reference with 0.1% initial accuracy is required in a compact SOT-23-5 footprint. Consider the 75 ppm/°C temperature drift for thermal stability needs. Evaluate the 60 µA operating current against system power budgets. Verify that the 20 mA maximum shunt current meets the load requirements of the target circuit design.

Voltage Reference Part Context

This part belongs to the LM4128 series of micropower precision shunt voltage references. The family offers various fixed output voltages and accuracy grades. The LM4128 series is widely used in general-purpose analog circuits where space and power efficiency are critical constraints alongside voltage stability.
