LM4132CMF-2.0/NOPB

Voltage Reference Overview

The LM4132CMF-2.0/NOPB is a precision series voltage reference from Texas Instruments, housed in a five-pin SOT-23 package. It provides a nominal output voltage of 2.048 V with an initial accuracy of ±0.2%. The device operates within an input voltage range up to 6 V and supports a maximum shunt current of 20 mA. Key performance metrics include a temperature coefficient of 30 ppm/°C and line regulation of 30 ppm/V. It functions reliably across a wide temperature range from -40°C to +125°C.

Voltage Reference Feature Summary

• Provides stable precision voltage reference output
• Integrates shutdown enable functionality for power management
• Utilizes low-profile surface-mount packaging

Voltage Reference Applications

• Portable instrumentation requiring precise voltage standards
• Battery-powered measurement systems
• Data acquisition circuits demanding high accuracy

Voltage Reference Procurement Notes

Verify the complete part number including the NOPB suffix to ensure compliance with lead-free manufacturing standards. Confirm that the required output voltage matches the specific application needs, as the LM4132 family offers various fixed voltage options. Ensure the selected package variant aligns with the intended PCB footprint and thermal requirements for the final design implementation.

Voltage Reference Selection Notes

Select this component when a compact form factor is required alongside high precision. The SOT-23-5 package suits space-constrained designs. Consider the ±0.2% initial accuracy and 30 ppm/°C drift for applications sensitive to temperature variations. Verify that the 20 mA maximum shunt current meets the load requirements of the connected circuitry without exceeding device limits.

Voltage Reference Part Context

This device belongs to the LM4132 family of micropower shunt voltage references. It shares architectural similarities with other members like the LM4132AMF and LM4132EMF, differing primarily in initial accuracy grades and temperature coefficients. The family is designed for applications needing stable references in small packages, serving as a benchmark for precision analog signal conditioning.

Voltage Reference Replacement Considerations

LM4132AMF-2.0/NOPB offers higher initial accuracy (±0.05%). LM4132EMF-2.0/NOPB provides improved temperature stability (20 ppm/°C). Both are pin-compatible alternatives within the same series.
