LM4050AIM3-10/NOPB

Voltage Reference Overview

The LM4050AIM3-10/NOPB is a precision shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 50 PPM/C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and is housed in an SOT-23-3 surface-mount package.

Voltage Reference Feature Summary

• Provides high-precision voltage referencing with 0.1% initial accuracy for critical measurement applications.
• Operates reliably across an extended industrial temperature range from -40°C to +125°C.
• Designed for space-constrained designs using a compact SOT-23-3 surface-mount package.

Voltage Reference Applications

• Precision data acquisition systems requiring stable reference voltages
• Battery-powered instrumentation utilizing low quiescent current operation
• Industrial control circuits demanding wide temperature stability

Voltage Reference Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against the manufacturer's latest documentation before ordering. Confirm that the 10 V output variant matches the circuit requirements, as this family offers multiple voltage options. Ensure the SOT-23-3 footprint aligns with the PCB layout specifications to prevent assembly errors during production.

Voltage Reference Selection Notes

Select this component when a 10 V reference with 0.1% accuracy is required. The 50 PPM/C temperature coefficient suits general precision applications. Consider the 15 mA maximum current capability for load driving needs. Verify compatibility with the system's operating temperature range up to 125°C. Compare against other LM4050 variants if different voltage or accuracy levels are needed.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references. The 'A' grade denotes the highest accuracy tier within the family. The 'IM3' indicates the SOT-23-3 package style. The 'NOPB' signifies lead-free construction without halogenated flame retardants. This series is designed for applications replacing larger through-hole references with compact surface-mount solutions.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4050AIM3-10/NOPB units from Texas Instruments. Alternative voltage values in the same package require changing the suffix number. Different accuracy grades (e.g., B or C) offer lower performance but may be available. Verify pinout compatibility when considering cross-brand alternatives.
