LM4040DIM3-8.2/NOPB

Overview

The LM4040DIM3-8.2/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in a compact SOT-23 package. It provides a fixed output voltage of 8.2V with an initial accuracy of 1%. The device features a temperature coefficient of 150 ppm/°C and operates within a junction temperature range of -40°C to +125°C. Key electrical specifications include a maximum cathode current of 15 mA and a minimum operating current of 100 µA. It is RoHS compliant and lead-free.

Feature Summary

Provides stable reference voltage in a miniature surface-mount package
Operates over extended industrial temperature ranges
Designed for low power consumption applications

Applications

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

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status against the latest manufacturer documentation. Ensure the ordering part number matches the required tolerance and temperature grade. Confirm availability through authorized distributors as supply levels may vary.

Selection Notes

Select this component when a fixed 8.2V reference is required in space-constrained designs. Consider the 1% initial accuracy and 150 ppm/°C drift for precision requirements. Verify that the circuit can maintain the minimum 100 µA cathode current for proper regulation.

Part Context

This part belongs to the LM4040-N series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages in small packages like SOT-23 and SC-70, targeting portable and battery-operated electronics where size and power efficiency are critical design factors.

Replacement Considerations

Check for direct equivalents such as LM4040AIM3-8.2/NOPB for tighter tolerance or LM4040CIM3-8.2/NOPB for different accuracy grades. Verify pinout compatibility and thermal characteristics before substitution.
