LM4040C82IDBZTG4

Overview

The LM4040C82IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 8.192 V with an initial accuracy of 0.5%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 15 mA and is housed in a SOT-23-3 surface-mount package.

Feature Summary

• Provides a stable 8.192 V reference voltage suitable for high-precision applications
• Operates across an extended industrial temperature range from -40°C to +125°C
• Designed for low power consumption with micropower shunt architecture

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition circuits

Procurement Notes

Verify the specific suffix IDBZT against official Texas Instruments documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as environmental declarations may vary by production batch. Ensure the component matches the required 8.192 V output and 0.5% accuracy tolerance for your design.

Selection Notes

Select this component when a fixed 8.192 V reference is required in a compact SOT-23-3 package. The 0.5% initial accuracy and 150 ppm/°C temperature coefficient define its precision class. Consider the 15 mA maximum shunt current limit for biasing requirements. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the LM4040 series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The C suffix typically denotes a specific accuracy bin, while the IDBZT indicates the SOT-23-3 package and reel packaging configuration.

Replacement Considerations

Check for direct substitutes within the LM4040 family offering the same 8.192 V output. Verify pinout compatibility and thermal performance if replacing with other manufacturers' equivalents.
