Overview
The LM4040DIZ-2.0/NOPB is a micropower shunt voltage reference by Texas Instruments, providing a fixed output of 2.048 V. It features an initial accuracy of 1% and operates within a temperature range of -40°C to +85°C. The device utilizes a TO-92 three-pin package for through-hole mounting. Key electrical parameters include a maximum shunt current of 15 mA, a minimum operating current of 73 µA, and a temperature coefficient of 150 ppm/°C.
Feature Summary
- Provides stable fixed voltage reference with high precision
- Operates in extreme temperature environments
- Low power consumption design
Applications
- Portable instrumentation circuits
- Battery-powered measurement systems
- Data acquisition signal conditioning
Procurement Notes
Verify the specific suffix 'D' indicates the 1% accuracy grade and 'I' denotes the industrial temperature range during procurement. Confirm the 'NOPB' designation ensures lead-free compliance and RoHS adherence. Cross-reference the manufacturer datasheet to validate pinout compatibility and thermal characteristics before finalizing orders.
Selection Notes
Select this component when a low-cost, through-hole voltage reference is required for general-purpose applications. The 1% tolerance suits designs that do not demand ultra-high precision. Ensure the circuit can accommodate the 15 mA maximum shunt current and verify that the TO-92 package fits the available board space constraints.
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 LM4040DIZ variant specifically targets cost-sensitive applications requiring moderate precision in a standard through-hole package, distinguishing it from higher-accuracy or surface-mount counterparts.
Replacement Considerations
Direct substitutes include LM4040AIM3-2.0/NOPB for surface mount needs or other LM4040 variants with matching voltage and package if through-hole is mandatory. Verify that any replacement maintains the 15 mA max shunt current and compatible temperature range.
