LM4040BIZ-10.0/NOPB

Overview

The LM4040BIZ-10.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed 10V output. It features an initial accuracy of ±0.2% and operates within a temperature range of -40°C to +85°C. The device utilizes a SOT-23 surface-mount package with three pins. Key electrical characteristics include a maximum shunt current of 15mA, a minimum cathode current of 70µA, and a temperature coefficient of 100ppm/°C. It is designed for precision applications requiring stable reference voltages in compact form factors.

Feature Summary

• Provides a precise fixed 10V reference voltage with high initial accuracy
• Operates as a micropower shunt regulator with low quiescent current consumption
• Engineered for stability across industrial temperature ranges

Applications

• Precision analog-to-digital converter (ADC) reference inputs
• Digital-to-analog converter (DAC) voltage references
• Battery-powered instrumentation circuits
• Portable measurement equipment requiring stable biasing

Procurement Notes

Verify the specific suffix 'BIZ' ensures the required ±0.2% accuracy grade and 100ppm/°C temperature coefficient. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the SOT-23-3 package matches the target PCB footprint. Cross-reference the manufacturer's latest datasheet for any pinout or marking changes before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 10V reference is required with tight tolerance specifications. The ±0.2% accuracy makes it suitable for high-precision data acquisition systems. Consider the 100ppm/°C drift rate for environments with significant thermal fluctuations. The SOT-23 package is ideal for space-constrained designs where through-hole alternatives are not feasible.

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 'B' grade denotes ±0.2% initial accuracy, while 'I' indicates industrial temperature range operation. The 'Z' suffix typically specifies the SOT-23 package type. This family is widely used in industrial and consumer electronics for stable voltage regulation.
