LM4132DMF-1.8/NOPB

Voltage Reference Overview

The LM4132DMF-1.8/NOPB is a precision series voltage reference from Texas Instruments, housed in a SOT-23-5 package. It provides a fixed output voltage of 1.8V with an initial accuracy of 0.05%. The device features a temperature coefficient of 20ppm/°C and supports a maximum input voltage of 6V. It operates within a junction temperature range of -40°C to +125°C and includes a shutdown enable function for power management.

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 enable pin to minimize current consumption during inactive periods

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage benchmarks
• Portable instrumentation powered by single-cell batteries

Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB and DMF against official Texas Instruments documentation to ensure correct package type and lead-free compliance. Confirm that the specific output voltage variant matches the design requirement, as the LM4132 family offers multiple fixed voltage options.

Voltage Reference Selection Notes

Select this component when designing circuits that demand high accuracy and low drift in a compact surface-mount footprint. The inclusion of a shutdown feature makes it suitable for battery-operated applications where quiescent current reduction is critical. Ensure the input voltage remains within the specified maximum limit relative to the output.

Voltage Reference Part Context

This device belongs to the LM4132 family of micropower shunt voltage references designed for space-constrained applications. The family utilizes bandgap technology to deliver precision performance in a small SOT-23 package, serving as a cost-effective alternative to larger reference components while maintaining high stability.

Voltage Reference Replacement Considerations

Compatible substitutes include other LM4132 variants with different fixed output voltages if the system allows for external adjustment or if the voltage level can be modified. Verify pinout compatibility before substitution.
