LM4132BMFX-2.5/NOPB

Voltage Reference Overview

The LM4132BMFX-2.5/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.1%. 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

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features low temperature drift characteristics for stable performance over wide thermal ranges
• Integrates shutdown enable functionality to minimize power consumption when inactive

Voltage Reference Applications

• Precision data acquisition systems requiring stable reference voltages
• Battery-powered instrumentation benefiting from low quiescent current operation
• Industrial process control loops demanding high accuracy and reliability

Voltage Reference Procurement Notes

Verify the specific suffix 'BMFX' corresponds to the required accuracy grade (±0.1%) and tape-and-reel packaging format. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance status as per the manufacturer's latest documentation before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside high precision. The 2.5 V output is suitable for single-supply ADCs. Ensure the application can accommodate the 20 mA maximum shunt current capability and that the 20 ppm/°C drift meets the system's long-term stability requirements.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower shunt voltage references. It shares the same pinout and general architecture with other variants in the series, differing primarily in output voltage options and accuracy grades. The family is designed for applications where space constraints and power efficiency are critical design factors.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4132 variants with matching 2.5 V output and similar accuracy, such as LM4132BIFX-2.5/NOPB or LM4132CIMF-2.5/NOPB, provided the package type and temperature coefficient specifications align with the original design requirements.
