LM4040CIZ-3.0/NOPB

Overview

The LM4040CIZ-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 3.0V with an initial accuracy of ±0.5%. It operates within a temperature range of -40°C to +85°C and features a maximum cathode current of 15mA. The device utilizes a TO-92-3 through-hole package and exhibits a temperature coefficient of 100ppm/°C.

Feature Summary

Provides stable reference voltage via shunt topology
Designed for low power consumption applications
Ensures precision performance across industrial temperatures

Applications

Portable instrumentation circuits
Battery-powered measurement systems
Data acquisition input conditioning

Procurement Notes

Verify the specific suffix 'I' indicates the TO-92 package variant distinct from SOT-23 versions. Confirm the 'C' grade corresponds to the ±0.5% tolerance specification. Ensure the 'NOPB' designation confirms lead-free and RoHS compliance status prior to ordering.

Selection Notes

Select this component when a through-hole mounting solution is required for space-constrained designs needing moderate precision. Compare against SOT-23 alternatives if surface mount technology is preferred. Evaluate thermal stability requirements against the 100ppm/°C coefficient for critical analog paths.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040CIZ variant specifically addresses applications requiring robust through-hole packaging for prototyping or legacy board designs.
