LM4040EIZ-2.0/NOPB

Overview

The LM4040EIZ-2.0/NOPB is a micropower shunt voltage reference by Texas Instruments, delivering a nominal output of 2.048 V. It operates within a temperature range of -40°C to +85°C and features an initial accuracy of ±1%. The device supports a maximum shunt current of 15 mA with a minimum operating current of 60 µA. Packaged in a TO-92 (TO-226AA) three-pin through-hole configuration, it exhibits a temperature coefficient of 150 ppm/°C.

Feature Summary

• Provides stable precision voltage referencing via a shunt topology
• Operates efficiently at micropower levels suitable for battery applications
• Ensures high stability across the industrial temperature range

Applications

• Portable instrumentation requiring precise analog references
• Battery-powered measurement systems
• Data acquisition circuits needing stable voltage sources

Procurement Notes

Verify the specific suffix 'EIZ' confirms the ±1% accuracy grade and TO-92 package variant. Confirm the '/NOPB' designation indicates lead-free and RoHS compliance status. Ensure the ordering part number matches the required voltage tolerance and thermal specifications for the target application environment.

Selection Notes

Select this component when a fixed 2.048 V reference is required in a through-hole format. The E-grade accuracy offers tighter tolerance than standard variants. Consider the 15 mA maximum current limit for load driving capabilities. Verify that the TO-92 footprint fits the PCB layout constraints compared to surface-mount alternatives.

Part Context

This device belongs to the LM4040 series of micropower shunt voltage references. The series provides various fixed output voltages and accuracy grades. The LM4040 family is designed for applications demanding low power consumption and high precision in compact packages.

Replacement Considerations

LM4040AIZ-2.0/NOPB: Offers higher accuracy (±0.1%) in the same package. LM4040CIZ-2.0/NOPB: Provides lower accuracy (±2%) in the same package.
