LM4040C50IDBZTG4

Overview

The LM4040C50IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy of ±0.5% and a temperature coefficient of 100ppm/°C. The device operates within a cathode current range of 45μA to 15mA and functions across an ambient temperature range of -40°C to 85°C. Packaged in a space-saving SOT-23-3 format, it requires no external capacitors for stability.

Feature Summary

• Provides stable reference voltage without requiring external output capacitors
• Maintains low dynamic impedance and noise characteristics
• Operates reliably across a wide operating current range

Applications

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

Procurement Notes

Verify the specific suffix 'G4' against the latest manufacturer documentation to confirm compliance with RoHS directives and lead-free status. Ensure the ordering part number matches the required package type and temperature grade specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V reference with 0.5% tolerance is required in a compact surface-mount footprint. Consider the industrial temperature range (-40°C to 85°C) and the minimum operating current requirements relative to the application's power budget and load conditions.

Part Context

This component belongs to the LM4040 series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and grades (A, B, C, D) to balance cost and performance. The 'C' grade indicates 0.5% accuracy, while the 'I' suffix denotes the industrial temperature range.
