LM4040A41IDBZR

Overview

The LM4040A41IDBZR 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 ±0.1% and a maximum 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

Offers high precision with tight output tolerances and low temperature coefficients suitable for demanding applications.
Operates as a shunt reference requiring minimal quiescent current, making it efficient for portable designs.
Maintains stability with all capacitive loads without the need for additional output capacitors.

Applications

Data-Acquisition Systems
Energy Infrastructure
Analog Input Modules
Field Transmitters

Procurement Notes

Verify the specific suffix 'DBZR' corresponds to the SOT-23 package and tape-and-reel delivery method. Confirm that the 'I' designation aligns with the required industrial temperature range of –40°C to 85°C for your specific environmental constraints. Ensure compatibility with existing PCB footprints for the three-pin surface-mount configuration.

Selection Notes

Select this component when a fixed 4.096V reference with high initial accuracy is required. The A-grade specification ensures superior performance compared to lower grades. Consider the low minimum operating current if power consumption is critical. Verify that the shunt topology fits the circuit design requirements regarding current sinking capabilities.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references from Texas Instruments. The series includes various fixed output voltages and accuracy grades (A, B, C, D) to provide flexibility in cost-to-performance ratios. The LM4040A41IDBZR represents the highest precision grade available for the 4.096V output option in the industrial temperature range.
