Voltage Reference Procurement Notes

Verify the exact suffix and package type when ordering, as variations exist within the LM4132 family. Confirm availability status directly with authorized distributors, as this specific variant may be discontinued or have limited stock. Ensure that the required tolerance and temperature coefficient specifications match your design needs before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when a fixed 2.048 V reference with tight initial accuracy and low drift is required. Consider the SOT-23-5 package size constraints and the 20 mA current capability. Evaluate if the 10 ppm/°C temperature coefficient meets your system's thermal stability requirements compared to other options in the series.

Voltage Reference Part Context

The LM4132AMFX-2.0 belongs to the LM4132 series of micropower series voltage references by Texas Instruments. These devices are designed to offer high precision in small packages, making them suitable for space-constrained applications. The series includes various output voltages and accuracy grades, with the AMFX variant specifically denoting the SOT-23-5 surface-mount package and 2.048 V output.

Voltage Reference Replacement Considerations

Check for direct substitutes like LM4132AMF-2.0/NOPB or LM4132EMFX-2.0/NOPB, ensuring pin compatibility and electrical parameter alignment. Verify if alternative packages or slightly different accuracies are acceptable for your application.
