LM4132CMFX-2.5/NOPB

Voltage Reference Overview

The LM4132CMFX-2.5/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.05% and a temperature coefficient of 20 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 enable function.

Voltage Reference Feature Summary

• Precision series voltage reference topology
• Integrated shutdown enable functionality
• High initial accuracy specification
• Low temperature coefficient for stability

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'CMFX' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the ordering code matches the required tolerance and packaging format. Cross-reference the part number with the latest Texas Instruments documentation to avoid discrepancies between legacy and updated revisions.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside high precision. The 2.5 V output suits applications interfacing with ADCs or DACs. Consider the 20 ppm/°C drift for thermal environments. Verify that the 20 mA max current meets load requirements. Compare with LM4132 variants if different output voltages or accuracies are needed.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The CMFX suffix indicates a specific tape-and-reel packaging option suitable for automated assembly processes in high-volume manufacturing environments.

Voltage Reference Replacement Considerations

LM4132CMF-2.5/NOPB: Same electrical specifications but in a non-flange SOT-23-5 package variant; verify mechanical fit. LM4132AMFX-2.5/NOPB: Higher accuracy grade (0.05%) available; check cost and availability differences.
