LM4040C10IDBZTG4

Overview

The LM4040C10IDBZTG4 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 average 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

• Delivers stable reference voltage with low dynamic impedance and low noise characteristics
• Operates without external output capacitors while remaining stable with all capacitive loads
• Utilizes fuse and Zener-zap reverse breakdown voltage trim for precise tolerance control

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 status and pinout compatibility. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with the thermal requirements of the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 10V reference with ±0.5% initial accuracy is required in a compact SOT-23-3 footprint. Ensure the design maintains cathode current above the 45μA minimum threshold to guarantee regulation stability. Consider the 100ppm/°C temperature coefficient for applications requiring moderate thermal stability over the industrial operating range.
