LM4040CIZ-5.0/NOPB

Overview

The LM4040CIZ-5.0/NOPB is a fixed shunt voltage reference from Texas Instruments, providing a nominal output of 5 V with an initial accuracy of ±0.5%. Housed in a TO-92 package, it operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100 ppm/°C. The device supports a maximum cathode current of 15 mA and is designed for surface-mount or through-hole integration depending on the specific variant configuration.

Feature Summary

Provides stable fixed voltage reference via shunt topology
Ensures precision performance with low temperature drift characteristics
Supports high cathode current capability for robust regulation

Applications

Precision analog-to-digital converter (ADC) reference inputs
Data acquisition system voltage references
Portable instrumentation power supply monitoring

Procurement Notes

Verify the exact suffix code against the manufacturer's official datasheet to confirm pinout compatibility and tolerance grade. Ensure the selected variant matches the required operating temperature range and package style for your specific PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V reference with moderate precision is required in a standard through-hole package. Consider the ±0.5% initial accuracy and 100 ppm/°C temperature coefficient against application stability needs. Verify that the 15 mA current limit suffices for the load requirements without exceeding thermal dissipation limits.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades, utilizing a bandgap reference architecture. It serves as a cost-effective solution for applications requiring stable voltage references in compact form factors.
