LM4040C10IDBZT

Overview

The LM4040C10IDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy of ±0.5%. The device operates within an ambient temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100ppm/°C. It requires a minimum cathode current of 45μA (typical) and supports a maximum continuous cathode current of 15mA. The component is housed in a space-saving SOT-23-3 surface-mount package.

Feature Summary

• Provides stable reference voltage without requiring external capacitors for operation
• Maintains low dynamic impedance and low noise characteristics across operating conditions
• Capable of driving all capacitive loads directly

Applications

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

Procurement Notes

Verify the specific suffix 'DBZT' corresponds to the SOT-23-3 package configuration during procurement. Confirm that the industrial temperature grade (-40°C to +85°C) meets the operational requirements, as extended temperature variants utilize different suffixes. Ensure compatibility with standard surface-mount assembly processes for the specified footprint.

Selection Notes

Select this component when a 10V fixed reference with 0.5% tolerance is required in a compact form factor. It is suitable for applications prioritizing low power consumption due to its micropower design. Consider the 100ppm/°C temperature coefficient for environments with moderate thermal variations. Verify that the load current remains within the recommended operating range to ensure stability.
