LM4132CMF-1.8/NOPB

Voltage Reference Overview

The LM4132CMF-1.8/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount package. It provides a fixed output voltage of 1.8 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a maximum input voltage of 6 V. Key electrical specifications include a maximum shunt current of 20 mA and a typical temperature coefficient of 30 ppm/°C.

Voltage Reference Feature Summary

• Provides stable reference voltage with high initial accuracy
• Operates over extended industrial temperature ranges
• Designed for low dropout performance in compact packages

Voltage Reference Applications

• Data acquisition systems requiring precise voltage references
• Portable instrumentation circuits
• Battery-powered measurement devices

Voltage Reference Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging configuration. Confirm that the SOT-23-5 footprint matches the target PCB layout. Ensure input voltage constraints are respected during system design to maintain specified accuracy levels.

Voltage Reference Selection Notes

Select this component when a 1.8 V reference is required with ±0.2% initial accuracy. Consider the 20 mA maximum shunt current limit for load requirements. The SOT-23-5 package is suitable for space-constrained designs compared to larger through-hole alternatives.

Voltage Reference Part Context

This component belongs to the LM4132 family of precision voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades, all sharing similar low-power characteristics and compact SOT-23 form factors designed for modern electronic applications.

Voltage Reference Replacement Considerations

Check for LM4132 variants with different output voltages or accuracy grades if 1.8 V is not strictly required. Verify pinout compatibility before substituting with other series references from different manufacturers.
