LM4132AMFX-4.1/NOPB

Voltage Reference Overview

The LM4132AMFX-4.1/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a surface-mount SOT-23-5 package. It provides a fixed output voltage of 4.096 V with an initial accuracy of 0.05%. The device features a temperature coefficient of 20 ppm/°C and supports a maximum shunt current of 20 mA. It operates within an input voltage range up to 6 V and functions across a temperature range from -40°C to +125°C.

Voltage Reference Feature Summary

• High precision voltage reference with 0.05% initial accuracy
• Low temperature drift of 20 ppm/°C for stable performance
• Integrated shutdown enable functionality for power management

Voltage Reference Applications

• Portable instrumentation requiring low power consumption
• Battery-powered measurement systems
• Data acquisition systems needing precise voltage references

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the 'F' suffix corresponds to the tape-and-reel packaging format intended for automated surface-mount assembly processes. Ensure the component matches the exact 4.096 V output variant required for the circuit design.

Voltage Reference Selection Notes

Select this component when high accuracy (0.05%) and low drift (20 ppm/°C) are critical requirements. The SOT-23-5 package suits space-constrained designs. Verify that the 20 mA maximum shunt current meets the load requirements and that the 6 V maximum input voltage aligns with the system supply rails.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references. The family includes various output voltages and accuracy grades, all sharing similar low-power characteristics and compact packaging options designed for portable and battery-operated applications.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4132 variants with matching 4.096 V output and 0.05% accuracy, such as LM4132AMF-4.1/NOPB, provided the packaging type (reel vs. cut tape) is compatible with the manufacturing process.
