LM4132AMF-2.0/NOPB

Voltage Reference Overview

The LM4132AMF-2.0/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 2.048 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 5.5 V. It operates within a junction temperature range of -40°C to +125°C and draws a typical quiescent current of 60 µA. The component includes a shutdown enable feature and can source up to 20 mA of load current.

Voltage Reference Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Integrates a shutdown control pin for power management flexibility
• Operates efficiently with low quiescent current consumption
• Designed for stable performance across extended industrial temperature ranges

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage benchmarks
• Battery-powered instrumentation with strict power constraints
• Medical equipment signal conditioning circuits

Voltage Reference Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging configuration. Confirm the AMF grade designation matches the required ±0.05% accuracy specification for your design. Check the datasheet for the correct SOT-23-5 footprint dimensions and thermal characteristics during PCB layout. Ensure input voltage limits are respected to maintain regulation integrity.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 form factor is required alongside high precision. The 2.048 V output is suitable for driving ADCs that utilize this standard reference level. Consider the 30 ppm/°C drift if operating in environments with significant thermal fluctuations. Compare against the LM4132CMF variant if lower cost is prioritized over tighter accuracy specifications.

Voltage Reference Part Context

This device 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 small outline package. The LM4132 series is designed to replace larger, less efficient reference solutions in space-constrained portable electronics and industrial control applications.

Voltage Reference Replacement Considerations

LM4132AMF-2.0 is the non-green equivalent predecessor. LM4132EMF-2.0/NOPB offers similar functionality with potentially different initial accuracy grades.
