Overview
The LM4040BIZ-2.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 2.048 V. It features an initial accuracy of ±0.2% and operates within a temperature range of -40°C to +85°C. The device utilizes a TO-92 three-pin package with a maximum shunt current of 15 mA and a minimum operating current of 60 µA. Its temperature coefficient is specified at 100 ppm/°C, ensuring stable performance in precision applications.
Feature Summary
- Provides a precise 2.048 V reference voltage with ±0.2% initial accuracy
- Operates as a micropower shunt regulator with low minimum current consumption
- Designed for high stability across industrial temperature ranges
Applications
- Precision analog-to-digital converter (ADC) references
- Data acquisition systems requiring stable voltage sources
- Battery-powered instrumentation circuits
Procurement Notes
Verify the specific suffix 'BIZ' corresponds to the required ±0.2% accuracy grade and TO-92 package variant. Confirm that the 2.048 V output matches the system design requirements. Ensure compatibility with existing thermal management strategies given the through-hole packaging. Check for any lead-free or RoHS compliance documentation if required by local regulations.
Selection Notes
Select this component when a fixed 2.048 V reference is needed with tight tolerance specifications. The TO-92 package is suitable for prototyping or applications where surface mount space is not constrained. Consider the 100 ppm/°C temperature coefficient against environmental conditions. Compare with series references if headroom voltage is limited, as shunt types require a minimum current path.
Part Context
This part belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The 'B' suffix typically denotes ±0.2% accuracy, while 'I' indicates the industrial temperature range. The 'Z' often specifies the TO-92 package style in this nomenclature.
Replacement Considerations
LM4040BIZ-2.0AMMOPACK is listed as a related document variant. Direct substitutes may include other LM4040 variants with matching voltage and accuracy, such as LM4040AIM3-2.0/NOPB for SOT-23 packages, provided pinout and electrical characteristics align.
