LM4132AMF-4.1/NOPB

Voltage Reference Overview

The LM4132AMF-4.1/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a surface-mount SOT-23-5 package. It provides a fixed output voltage of 4.096 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 quiescent current of 60 µA.

Voltage Reference Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances for sensitive analog circuits.
• Incorporates a shutdown enable feature to minimize power consumption during inactive periods.
• Utilizes a compact SOT-23-5 footprint suitable for space-constrained printed circuit board layouts.

Voltage Reference Applications

• Portable instrumentation requiring low power consumption
• Data acquisition systems needing stable reference voltages
• Battery-powered measurement devices

Voltage Reference Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering code matches the required accuracy grade and packaging format. Cross-reference the component marking with official documentation to prevent counterfeit substitution.

Voltage Reference Selection Notes

Select this component when a 4.096 V reference with ±0.05% accuracy is required in a small form factor. Consider the 6 V maximum input limit and 20 mA shunt current capability during circuit design. Evaluate thermal performance within the specified -40°C to +125°C operating range for the target environment.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades within the same SOT-23-5 package. The 'AMF' designation indicates the specific accuracy class and tape-and-reel packaging configuration.

Voltage Reference Replacement Considerations

LM4132AMF-4.1/NOPB serves as a direct replacement for older National Semiconductor versions of the same part number. Verify pinout compatibility when substituting with other 4.096 V references in the LM4132 series.
