LM4040C41IDBZTG4

Overview

The LM4040C41IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096V with an initial accuracy of 0.5%. The device operates within an extended temperature range from -40°C to +125°C and features a maximum temperature coefficient of 100ppm/°C. Packaged in a space-saving SOT-23-3 format, it requires a minimum cathode current of 45μA typical and supports up to 15mA. The component is RoHS compliant and designed for stable operation across wide operating currents.

Feature Summary

Maintains stable output voltage over a wide range of operating currents and temperatures
Operates without requiring external output capacitors
Provides low dynamic impedance and low noise performance
Utilizes 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 ordering suffix 'G4' against the latest manufacturer documentation to confirm compliance details and package options. Ensure the selected grade matches the required initial accuracy and temperature coefficient specifications for the target application environment.

Selection Notes

Select this component when a fixed 4.096V reference with 0.5% tolerance is required in an SOT-23-3 package. Consider the extended temperature range capability for harsh environments. Verify that the circuit design accommodates the minimum cathode current requirement for proper regulation.

Part Context

This part belongs to the LM4040 series of shunt voltage references. The series offers various fixed output voltages including 2.048V, 2.5V, 3V, 5V, 8.192V, and 10V. Different grades (A, B, C, D) provide varying levels of initial accuracy and temperature coefficients to suit different cost-performance requirements.
