LM4040D50IDBZTG4

Overview

The LM4040D50IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy of 1% and a temperature coefficient of 150 ppm/°C. The device operates within a cathode current range of 45μA to 15mA and functions across an extended temperature range from -40°C to +125°C. Packaged in a space-saving SOT-23-3 format, it requires no external capacitors for stability.

Feature Summary

• Stable with all capacitive loads without requiring an output capacitor
• Low dynamic impedance and low noise characteristics
• Fuse and Zener-zap reverse breakdown voltage trim during wafer sort

Applications

• Data-Acquisition Systems
• Energy Infrastructure
• Analog Input Module
• Field Transmitters
• Precision Audio

Procurement Notes

Verify the specific suffix 'TG4' against the manufacturer's latest documentation to confirm RoHS compliance and packaging details. Ensure the D-grade specifications align with system requirements before procurement. Confirm availability status as product lifecycles may change.

Selection Notes

Select this component when a 5V reference with 1% tolerance is required in an extended temperature environment. The D-grade offers a balance of cost and performance suitable for general-purpose applications where tighter tolerances are not critical. Verify that the minimum operating current meets the circuit design constraints.

Part Context

This part belongs to the LM4040 series of shunt voltage references. The 'D' indicates the D-grade with 1% accuracy and 150 ppm/°C temperature coefficient. The '50' denotes the 5V output voltage. The 'I' specifies the industrial temperature range (-40°C to 85°C), while the 'Q' variant covers the extended range (-40°C to 125°C). This specific part number includes the 'G4' suffix indicating lead-free and RoHS compliant packaging.
