LM4040A10IDBZRG4

Overview

The LM4040A10IDBZRG4 is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed output of 10V. It belongs to the A-grade series, offering an initial accuracy of ±0.1% and a maximum temperature coefficient of 100ppm/°C within the industrial temperature range of -40°C to 85°C. The device operates with a cathode current range from 45μA to 15mA and is housed in a space-saving SOT-23 package.

Feature Summary

• Provides high-precision voltage referencing with tight initial tolerance and low temperature drift for stable performance across varying conditions.
• Operates efficiently at micropower levels, requiring minimal quiescent current suitable for battery-powered or energy-constrained applications.
• Maintains stability with any capacitive load without requiring external compensation components, simplifying circuit design.

Applications

• Data-acquisition systems
• Energy infrastructure monitoring
• Analog input modules
• Field transmitters

Procurement Notes

Verify the specific ordering suffix 'RG4' against the manufacturer's latest Package Option Addendum to confirm reel packaging details and RoHS compliance status. Ensure the component matches the required A-grade specifications for initial accuracy and temperature coefficient before integration into production designs.

Selection Notes

Select this component when a 10V reference with high precision (±0.1%) is required in a compact SOT-23 footprint. It is suitable for industrial environments (-40°C to 85°C) where low power consumption and stability under varying capacitive loads are critical design constraints.

Part Context

This part is a member of the LM4040 family of shunt voltage references. The 'A' designation indicates the highest precision grade available in the series, while '10' specifies the 10V output voltage. The 'DBZR' indicates the SOT-23 surface-mount package, and 'G4' typically denotes lead-free and environmental compliance attributes.
