LM4132AMFX-3.0/NOPB

Voltage Reference Overview

The LM4132AMFX-3.0/NOPB is a precision series voltage reference from Texas Instruments, housed in an SOT-23-5 surface-mount package. It provides a fixed output voltage of 3 V with an initial accuracy of 0.05% and a temperature coefficient of 30 ppm/°C. The device supports a maximum input voltage of 6 V and a maximum shunt current of 20 mA. It operates within a temperature range of -40°C to +125°C and features a shutdown capability with a typical supply current of 60 µA.

Voltage Reference Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance.
• Includes a dedicated shutdown pin for power management control.
• Operates reliably across extended industrial temperature ranges.

Voltage Reference Applications

• Portable instrumentation requiring low power consumption
• Battery-powered measurement systems
• Data acquisition systems needing stable reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix 'AMFX' against official Texas Instruments documentation to confirm the exact accuracy grade and tape-and-reel packaging configuration. Ensure the ordering part number matches the required initial accuracy and thermal performance specifications for your design.

Voltage Reference Selection Notes

Select this component when a 3 V reference with 0.05% initial accuracy is required in a compact SOT-23-5 footprint. Consider the 6 V maximum input voltage limit and 20 mA shunt current capability during circuit design to ensure proper biasing and thermal operation within the specified temperature range.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references. It shares the same functional architecture as other variants in the series but is distinguished by its specific 3 V output voltage, 0.05% accuracy grade, and SOT-23-5 surface-mount packaging optimized for space-constrained applications.

Voltage Reference Replacement Considerations

LM4132EMF-3.0/NOPB offers similar functionality with 0.5% accuracy in the same package.
