LM4041BIDCKT

Overview

The LM4041BIDCKT is a precision micropower shunt voltage reference from Texas Instruments, housed in an SC-70-5 surface-mount package. It provides an adjustable output voltage ranging from 1.225 V to 10 V using external resistors. The device features B-grade accuracy with an initial tolerance of ±0.2% and a temperature coefficient of 100 ppm/°C. It operates within a current range of 80 µA to 12 mA and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Adjustable output voltage configuration via external resistor divider
• Stable operation with any capacitive load without external compensation
• Low dynamic impedance for consistent performance across operating currents

Applications

• Data acquisition systems requiring stable reference voltages
• Battery-powered portable equipment
• Precision audio applications

Procurement Notes

Verify the specific suffix 'CKT' against the official datasheet to confirm the reel quantity and tape specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the SC-70-5 package dimensions align with your PCB footprint constraints before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require an adjustable precision reference. The SC-70-5 package offers a compact solution compared to larger packages. Verify that the required output voltage falls within the 1.225 V to 10 V range and that the ±0.2% accuracy meets system specifications.

Part Context

This part belongs to the LM4041-N family of micropower shunt references. It shares core architectural features with other variants like the LM4040 series but differs in package type and adjustability. The LM4041 specifically supports adjustable outputs, whereas some siblings offer fixed voltages.

Replacement Considerations

Check for direct substitutes such as LM4041BIDCKR or LM4041BIDCKTE4. Verify pinout compatibility and electrical parameter equivalence before substitution.
