LM4132DMFX-3.0/NOPB

Voltage Reference Overview

The LM4132DMFX-3.0/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 3.0 V with an initial accuracy of ±0.05%. The device features a temperature coefficient of 20 ppm/°C and supports a maximum input voltage of 6 V. It operates within a junction temperature range of -40°C to +125°C and includes a shutdown enable feature for power management.

Voltage Reference Feature Summary

• High precision with 0.05% initial accuracy
• Integrated shutdown control for power optimization
• Low dropout operation capability

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 'DMF' against official Texas Instruments documentation to confirm pinout and marking consistency. Ensure the 'NOPB' designation confirms lead-free and RoHS compliance status as per current manufacturing standards. Cross-reference the exact part number with the latest datasheet revision to avoid discrepancies in electrical specifications or packaging details.

Voltage Reference Selection Notes

Select this component when high accuracy (0.05%) and low drift (20 ppm/°C) are critical requirements. The integrated shutdown function makes it suitable for battery-operated devices where standby power reduction is necessary. Compare its performance against the EMF variant if higher accuracy is not required but cost sensitivity is a factor.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower shunt voltage references. It shares architectural similarities with other members like the LM4132EMF and LM4132AMFX, differing primarily in initial accuracy grades and specific output voltage options. The family is designed for applications requiring stable references in compact surface-mount packages.

Voltage Reference Replacement Considerations

LM4132EMF-3.0/NOPB offers similar functionality with slightly lower accuracy (0.5%). LM4132AMFX-3.0/NOPB provides comparable accuracy but may differ in maximum input voltage ratings. Verify pin compatibility and thermal characteristics before substitution.
