LM4132CMFX-3.0/NOPB

Voltage Reference Overview

The LM4132CMFX-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 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

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Incorporates a shutdown enable pin to reduce current consumption during inactive periods
• Designed for low noise performance suitable for sensitive analog signal chains

Voltage Reference Applications

• Precision data acquisition systems requiring stable reference voltages
• Battery-powered instrumentation benefiting from low quiescent current operation
• Medical equipment demanding high accuracy and reliability in signal conditioning

Voltage Reference Procurement Notes

Verify the specific suffix 'CMFX' against the manufacturer's official datasheet to confirm the exact accuracy grade and packaging type. Ensure the ordering part number matches the required initial accuracy and thermal specifications for your design. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or Texas Instruments before finalizing procurement plans.

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 20 ppm/°C temperature coefficient for applications operating across wide temperature ranges. Evaluate the shutdown functionality if power conservation is critical compared to standard non-shutdown variants in the LM4132 family.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower shunt voltage references from Texas Instruments. It shares the same core architecture as other LM4132 variants but is distinguished by its specific output voltage, accuracy grade, and surface-mount packaging configuration designed for automated assembly processes.
