LM4040BIZ-5.0/NOPB

Overview

The LM4040BIZ-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, offering a fixed 5V output with ±0.2% initial accuracy and a temperature coefficient of 100 ppm/°C. It operates within a -40°C to +85°C range in a TO-92 package.

Feature Summary

• Provides stable precision voltage referencing via a shunt topology
• Ensures high accuracy with tight initial tolerance specifications
• Maintains performance stability across wide industrial temperature variations

Applications

• Precision analog-to-digital converter references
• Battery-powered instrumentation circuits
• Portable measurement equipment power supplies

Procurement Notes

Verify the specific suffix 'I' indicates the TO-92 package variant distinct from SOT-23 versions. Confirm AEC-Q100 qualification status if automotive compliance is required for your specific design implementation.

Selection Notes

Select this component when a fixed 5V reference is needed in a through-hole TO-92 form factor. Ensure circuit design accommodates the shunt configuration requiring a series current-limiting resistor for proper operation.

Part Context

Part of the LM4040 family of micropower shunt references. The 'B' grade denotes tighter accuracy than standard grades, while 'I' specifies the plastic TO-92 package suitable for general-purpose prototyping and industrial applications.
