LM4132AMF-2.0

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 function 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
• Features low temperature drift characteristics for stable performance across wide thermal ranges
• Integrates a shutdown control pin to minimize power consumption during inactive periods

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix (e.g., NOPB) to confirm lead-free compliance and packaging type. Ensure the input voltage does not exceed the absolute maximum rating of 5.5 V to prevent device damage. Confirm the required accuracy grade matches the AMF variant specifications before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside high precision. Compare against the LM4132EMF variant if lower cost is prioritized over tighter accuracy tolerances. Consider the LM4132CMF variant only if relaxed accuracy specifications are acceptable for the application design constraints.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower shunt voltage references designed for space-constrained applications. It serves as a direct replacement for older National Semiconductor versions while offering improved thermal stability. The device is categorized under PMIC voltage references within Texas Instruments' portfolio.

Voltage Reference Replacement Considerations

LM4132AMF-2.0/NOPB is the direct lead-free equivalent of the LM4132AMF-2.0. Verify pin compatibility when substituting with other series references from different manufacturers.
