LM4050AIX3-3.3

Voltage Reference Overview

The LM4050AIX3-3.3 is a precision two-terminal shunt-mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown output voltage of 3.3V with an initial accuracy of ±0.1%. The device features a maximum temperature coefficient of 50ppm/°C, guaranteed over the operating temperature range of -40°C to +125°C. It operates within a wide current range from 60µA to 15mA and is housed in a subminiature 3-pin SC-70 surface-mount package.

Voltage Reference Feature Summary

• Ultra-small 3-pin SC-70 package for space-critical applications
• High initial accuracy of ±0.1% ensured by laser-trimmed resistors
• Wide operating current range supporting low-power designs
• Stable performance without requiring external stabilizing capacitors

Voltage Reference Applications

• Portable battery-powered equipment
• Notebook computers
• Cell phones
• Industrial process controls
• Automotive systems

Voltage Reference Procurement Notes

Verify the specific suffix 'IX3' against official manufacturer documentation, as standard listings typically utilize 'EX3' for the SC-70 package. Confirm availability status directly with Analog Devices or authorized distributors, as supply constraints may apply to this component family. Ensure the ordering part number matches the required tolerance grade and packaging format.

Voltage Reference Selection Notes

Select this component when high precision and minimal board space are required. The ±0.1% accuracy and 50ppm/°C temperature coefficient make it suitable for sensitive analog circuits. Verify that the load current remains within the 60µA to 15mA operational window to maintain specified stability and noise performance characteristics.

Voltage Reference Part Context

This device belongs to the LM4050/LM4051 series of micropower shunt voltage references. The series offers multiple fixed reverse breakdown voltages including 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. The 'A' grade denotes the highest accuracy tier within the product line.

Voltage Reference Replacement Considerations

Compatible substitutes include other LM4050 variants with different voltage outputs or packages, such as LM4050CEX3-3.3+T (0.5% accuracy) or LM4050AEX3-3.3+T. Cross-reference pinouts and thermal specifications before substitution.
