LM4050AIM3-10

Voltage Reference Overview

The LM4050AIM3-10 is a precision micropower shunt voltage reference manufactured by Texas Instruments, which acquired National Semiconductor. It provides a fixed reverse breakdown voltage of 10V with an initial accuracy of 0.1%. The device features a maximum temperature coefficient of 50ppm/°C and operates over an extended temperature range from -40°C to +125°C. It supports a shunt current range up to 15mA and utilizes a compact SOT-23 surface-mount package.

Voltage Reference Feature Summary

• Provides stable reference voltage via two-terminal shunt operation
• Ensures high precision through laser-trimmed internal resistors
• Maintains stability across wide operating currents without external capacitors
• Operates reliably in extreme industrial temperature environments

Voltage Reference Applications

• Precision data acquisition systems requiring stable reference voltages
• Battery-powered instrumentation benefiting from low power consumption
• Handheld measurement devices where space constraints are critical
• Industrial process control loops demanding high accuracy

Voltage Reference Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Confirm that the specific suffix indicates the correct voltage grade and package type. Ensure compatibility with RoHS standards if required for your region. Check for obsolescence notices or recommended new replacements before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when a 10V reference is specifically required with high initial accuracy. Consider the SOT-23 package size for space-constrained designs. Evaluate the 15mA current capability against load requirements. Verify that the 50ppm/°C temperature coefficient meets the system's thermal stability needs across the full operating range.

Voltage Reference Part Context

This part belongs to the LM4050 family of precision micropower shunt voltage references. The family offers various fixed voltage options in small packages. The 'A' grade denotes tighter initial accuracy specifications compared to lower grades. The 'M3' suffix typically indicates the SOT-23 package configuration used in modern surface-mount applications.

Voltage Reference Replacement Considerations

Check for direct equivalents within the LM4050 series offering different voltage outputs if 10V is not strictly mandatory. Consider TL4050 variants for similar performance characteristics. Verify pinout compatibility before substituting with other manufacturers' shunt references.
