Overview
The LM4040D30IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3 V with an initial accuracy of 1%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 150 PPM/°C. Electrical specifications include a maximum shunt current of 15 mA and a minimum operating current of 65 µA. It is housed in a SOT-23-3 surface-mount package.
Feature Summary
- Provides a stable 3 V reference voltage for circuit applications
- Operates across an extended industrial temperature range
- Designed for low power consumption with micropower characteristics
Applications
- Portable instrumentation systems requiring precise voltage references
- Battery-powered measurement devices
- Data acquisition systems needing stable analog references
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the component is available in cut tape or reel formats suitable for automated assembly. Check for any obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.
Selection Notes
Select this component when a 3 V fixed reference with 1% accuracy is required. Ensure the application current does not exceed the 15 mA maximum limit. Verify that the SOT-23-3 package fits the design constraints. Consider the 150 PPM/°C temperature coefficient against thermal stability requirements.
Part Context
This part belongs to the LM4040 series of precision micropower shunt voltage references. It shares the same form factor and basic functionality as other variants in the family, differing primarily in output voltage and accuracy grades. It serves as a compact solution for replacing bulkier reference components in space-constrained designs.
Replacement Considerations
LM4040D30IDBZR is a compatible alternative within the same series offering identical electrical performance and pinout configuration.
