LM4050CIX3-4.1-T

Voltage Reference Overview

The LM4050CIX3-4.1-T is a precision micropower shunt voltage reference manufactured by Analog Devices / Maxim Integrated. It provides a fixed reverse breakdown voltage of 4.096V with an initial accuracy of 0.5%. The device features a maximum temperature coefficient of 50ppm/°C, guaranteed over the industrial temperature range of -40°C to +125°C. It operates within a wide shunt 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 designs
• Laser-trimmed resistors ensure stable initial accuracy without external capacitors
• Capable of tolerating capacitive loads while maintaining stability

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'C' grade corresponds to the 0.5% initial accuracy specification. Ensure the manufacturer designation matches Analog Devices or Maxim Integrated as per the latest component documentation. Check for any AEC-Q100 automotive qualification status if required for the application.

Voltage Reference Selection Notes

Select this component when a 4.096V reference is needed in a minimal footprint. The 0.5% accuracy grade offers a balance between cost and performance for general-purpose applications. Verify that the operating current remains within the 60µA to 15mA window to maintain specified temperature coefficients and noise characteristics.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of two-terminal bandgap voltage references. The series is designed to replace larger packages like SOT-23, offering 50% smaller size. It serves as a direct replacement for legacy shunt references requiring high precision in compact mobile and industrial form factors.

Voltage Reference Replacement Considerations

LM4050AIM3X-4.1/NOPB (Texas Instruments) offers similar functionality with 0.1% accuracy in an SOT-23-3 package. LM4050CEX3-4.1+ (Maxim) provides identical electrical specifications and package type.
