LM4050AIX3-2.1-T

Voltage Reference Overview

The LM4050AIX3-2.1-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 2.048V 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 utilizes a compact SC-70-3 surface-mount package.

Voltage Reference Feature Summary

• Ultra-small 3-pin SC-70 surface-mount package for space-critical applications
• Laser-trimmed resistors ensure high initial accuracy
• Capable of tolerating capacitive loads without external stabilizing capacitors

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'IX3' against official manufacturer documentation to confirm pinout compatibility and exact electrical specifications, as variations exist within the LM4050 family. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering information in the datasheet to validate the availability of the 2.048V variant in the specified package configuration.

Voltage Reference Selection Notes

Select this component when a stable 2.048V reference is required in a minimal footprint. The 0.1% accuracy grade suits applications demanding high precision. Consider the 60µA minimum operating current for low-power designs. Verify that the load capacitance does not exceed stability limits defined in the datasheet, although the device is designed to tolerate such loads.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 series of precision two-terminal shunt-mode bandgap 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

LM4050CEX3-2.048+T: Offers similar functionality but with 0.5% initial accuracy instead of 0.1%. LM4050AEX3-2.5+T: Provides a different fixed voltage output (2.5V) while maintaining the same package and accuracy grade.
