LM4132AMF-2.5/NOPB

Voltage Reference Overview

The LM4132AMF-2.5/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a compact SOT-23-5 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.05%. The device features a low 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 reliably across an extended 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 varying thermal conditions
• Integrates shutdown functionality to minimize power consumption when not in use

Voltage Reference Applications

• Portable instrumentation requiring precise analog-to-digital conversion references
• Battery-powered measurement systems needing low quiescent current operation

Voltage Reference Procurement Notes

Verify the specific suffix codes against official Texas Instruments documentation to ensure correct pinout and functional configuration. Confirm that the ordering part number matches the required output voltage and accuracy grade. Check for RoHS compliance status and packaging options such as cut tape or reel quantities. Ensure the component meets the environmental specifications required for the intended operating temperature range.

Voltage Reference Selection Notes

Select this component when a small form factor is critical alongside high precision requirements. Compare the 30 ppm/°C temperature coefficient against application stability needs. Evaluate the 20 mA maximum shunt current capability against load requirements. Consider the SOT-23-5 package dimensions for PCB layout constraints relative to other available voltage reference families.

Voltage Reference Part Context
