LM4132BMF-4.1/NOPB

Voltage Reference Overview

The LM4132BMF-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 0.1%. The device features a temperature coefficient of 30 ppm/°C and supports a maximum shunt current of 20 mA. It operates within an input voltage range up to 6 V and functions across a temperature range from -40°C to +125°C.

Voltage Reference Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features low temperature drift characteristics for stable performance over wide thermal ranges
• Includes shutdown functionality to minimize power consumption when not in use

Voltage Reference Applications

• Portable instrumentation requiring low power consumption
• Data acquisition systems needing precise voltage references
• Battery-powered measurement devices

Voltage Reference Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct voltage and accuracy grades. Confirm RoHS compliance status as indicated in manufacturer documentation. Check for any process change notifications that may affect pinout or electrical specifications before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside high precision. Ensure the system input voltage remains below the maximum limit of 6 V. Consider the 20 mA shunt current capability for load requirements. Verify that the 30 ppm/°C temperature coefficient meets the application's stability needs.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower shunt voltage references. It shares the same physical package and general topology as other variants in the series but differs in output voltage and accuracy grades. The 'BMF' designation indicates specific performance tiers within the product line.

Voltage Reference Replacement Considerations

LM4132AMF-4.1/NOPB offers higher accuracy (0.05%) with similar packaging. LM4132EMF-4.1/NOPB provides lower accuracy (0.5%) at potentially different cost points. Cross-reference datasheets for exact electrical parameter compatibility.
