LM4040DIM3-8.2/NOPB

Overview

The LM4040DIM3-8.2/NOPB is a precision micropower shunt voltage reference with an output voltage of 8.192 V and initial accuracy of 1%. It operates with a cathode current of 96 µA and supports a maximum shunt current of 15 mA. The device features a temperature coefficient of 150 ppm/°C and noise of 130 µVrms (10Hz to 10kHz). It is housed in a SOT-23 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

Micropower operation with low quiescent current for energy efficiency
High precision with 1% initial accuracy and stable voltage regulation
Compact surface-mount packaging suitable for space-constrained designs

Applications

Portable battery-powered instrumentation
Space-critical embedded systems
Precision measurement circuits requiring stable reference voltages

Procurement Notes

Verify the manufacturer designation, as Texas Instruments acquired National Semiconductor. Confirm the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence. Ensure the package type matches the required SOT-23 footprint for PCB layout compatibility.

Selection Notes

Select this component when a fixed 8.192 V reference is required with minimal power consumption. Consider the 15 mA maximum shunt current limit for load driving capabilities. Evaluate the 150 ppm/°C temperature coefficient against environmental stability requirements.

Part Context

This part belongs to the LM4040 series of precision shunt voltage references. It serves as a compact alternative to larger voltage reference components, offering high accuracy in a small form factor. The series includes various output voltages and packages to suit diverse electronic design needs.

Replacement Considerations

LM4040DIM3-8.2/DIS is the non-RoHS equivalent. Other LM4040 variants with different output voltages or packages may serve as functional substitutes if electrical parameters align with circuit requirements.
