LM4132CMF-4.1/NOPB

Voltage Reference Overview

The LM4132CMF-4.1/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 4.096 V with an initial accuracy of ±0.2%. The device features a maximum 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 a stable 4.096 V reference output with high initial accuracy
• Features low temperature drift for consistent performance over varying thermal conditions
• Includes a shutdown enable pin for power management control

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage references
• Portable instrumentation powered by battery supplies

Voltage Reference Procurement Notes

Verify the specific suffix 'CMF' indicates the ±0.2% accuracy grade and 4.096 V output during procurement. Confirm the 'NOPB' designation ensures compliance with RoHS standards and absence of lead. Ensure the SOT-23-5 package type matches the target PCB footprint requirements before finalizing orders.

Voltage Reference Selection Notes

Select this component when a fixed 4.096 V reference with ±0.2% initial accuracy is required. It is suitable for applications needing low temperature drift and compact SOT-23-5 packaging. Consider the 20 mA maximum shunt current limit and 6 V maximum input voltage constraints during circuit design to ensure proper operation within specified limits.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades, all sharing similar low-power characteristics and compact SOT-23-5 packaging options designed for space-constrained electronic designs.

Voltage Reference Replacement Considerations

LM4132AMF-4.1/NOPB: Offers higher accuracy at ±0.05% but shares identical electrical parameters and package.
