LM4050CIM3X-2.0/NOPB

Voltage Reference Overview

The LM4050CIM3X-2.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 2.048 V. It operates within an extended temperature range from -40°C to +125°C and offers an initial accuracy of 0.5%. The device utilizes a SOT-23-3 surface-mount package and supports a maximum shunt current of 15 mA with a low operating current of 90 µA. Its temperature coefficient is specified at 50 ppm/°C, ensuring stable performance across varying thermal conditions.

Voltage Reference Feature Summary

• Provides a fixed 2.048 V reference output with high precision
• Operates over an extended industrial temperature range up to 125°C
• Features low power consumption suitable for battery-powered applications

Voltage Reference Applications

• Portable instrumentation requiring precise voltage references
• Battery-operated measurement systems
• Data acquisition systems needing stable analog references

Voltage Reference Procurement Notes

Verify the specific suffix 'CIM3X' against the official datasheet to confirm the exact tolerance and temperature grade. Ensure the ordering part number matches the required AEC-Q100 qualification if automotive compliance is necessary. Confirm package type and reel specifications prior to procurement.

Voltage Reference Selection Notes

Select this component when a fixed 2.048 V reference is required in a compact SOT-23-3 package. It is suitable for designs demanding low quiescent current and stability over a wide temperature range. Compare with the LM4040 series if lower cost or different accuracy levels are acceptable for the application.

Voltage Reference Part Context

This part belongs to the LM4050 family of micropower shunt voltage references. It shares the same functional architecture as other variants in the series but is distinguished by its specific 2.048 V output voltage and 0.5% initial accuracy. The family is designed for applications where space and power efficiency are critical constraints.

Voltage Reference Replacement Considerations

LM4050AIM3X-2.0/NOPB offers higher accuracy (0.1%) and similar form factor. LM4040CIM3X-2.0/NOPB provides a similar function but with a wider temperature coefficient and limited to 85°C operation.
