LM4040BIZ-4.1/NOPB

Overview

The LM4040BIZ-4.1/NOPB is a micropower shunt voltage reference manufactured by National Semiconductor, now part of Texas Instruments. It provides a fixed output voltage of 4.1V with an initial accuracy of 0.2%. The device features a maximum temperature coefficient of 150 ppm/°C and operates within a temperature range of -40°C to +85°C. It utilizes a TO-92 package and supports a maximum shunt current of 15 mA.

Feature Summary

Provides stable reference voltage with high precision
Operates in industrial temperature environments
Designed for low power consumption applications

Applications

Precision measurement systems
Portable instrumentation
Battery-powered devices

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments on the component marking. Confirm the specific suffix indicates lead-free compliance and RoHS status. Ensure the package type matches the required TO-92 form factor for your PCB layout. Cross-reference the datasheet revision to confirm electrical characteristics align with your design requirements.

Selection Notes

Select this component when a fixed 4.1V reference is required with 0.2% initial accuracy. Consider the 150 ppm/°C temperature coefficient for thermal stability needs. The TO-92 package suits through-hole mounting constraints. Evaluate the 15 mA maximum shunt current against circuit load requirements to ensure proper operation within safe limits.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed output voltages including 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V. Different suffixes denote accuracy grades such as A (0.1%), B (0.2%), C (0.5%), and D (1%). The LM4040 series is designed for applications requiring stable reference voltages over wide temperature ranges.
