LM4132AMF-3.0/NOPB

Voltage Reference Overview

The LM4132AMF-3.0/NOPB is a precision series voltage reference from Texas Instruments, housed in a 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 30 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 draws a typical supply current of 60 µA.

Voltage Reference Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features low temperature drift characteristics for stable performance across wide thermal ranges
• Includes shutdown enable functionality to minimize power consumption during idle states

Voltage Reference Applications

• Portable battery-powered instrumentation requiring low quiescent current
• Data acquisition systems needing precise analog-to-digital conversion references
• Medical equipment requiring stable voltage sources in compact form factors

Voltage Reference Procurement Notes

Verify the specific suffix 'AMF' indicates the A-grade accuracy variant (±0.05%) compared to standard E-grade parts. Confirm the 'NOPB' designation ensures compliance with RoHS directives and absence of lead-based materials. Ensure the ordering part number matches the required initial accuracy and package type for your design specifications.

Voltage Reference Selection Notes

Select this component when designs demand tighter initial accuracy than standard variants offer. The A-grade specification suits applications where calibration overhead must be minimized. Consider the 6 V maximum input limit and 20 mA shunt current capability when designing the biasing network for optimal noise and stability performance.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references. It shares the same pinout and basic architecture as other variants but distinguishes itself through the A-grade accuracy binning. The family is designed for space-constrained applications requiring high precision without significant power penalty.

Voltage Reference Replacement Considerations

LM4132EMF-3.0/NOPB offers similar functionality with lower initial accuracy (±0.5%). LM4132DMF-3.0/NOPB provides even looser tolerance. Verify that the reduced accuracy of these alternatives meets your system requirements before substitution.
