LM4041CIDCKT

Overview

The LM4041CIDCKT is a precision shunt voltage reference from Texas Instruments, housed in a SC-70-5 surface-mount package. It features an adjustable output voltage range of 1.225 V to 10 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and exhibits a typical temperature coefficient of 100 ppm/°C. Key electrical parameters include a maximum cathode current of 12 mA, a minimum operating current of 45 µA, and a typical output noise of 20 µVRMS. Designed for stability without external capacitors, it supports wide dynamic impedance performance across varying loads.

Feature Summary

• Adjustable output voltage capability ranging from 1.225 V to 10 V via external resistors
• Inherent stability with any capacitive load, eliminating the need for external stabilizing capacitors
• Low dynamic impedance and low noise characteristics ensure stable reverse breakdown voltage accuracy
• Sub-miniature SC-70-5 packaging designed for space-critical portable applications

Applications

• Data acquisition systems requiring precise voltage references
• Power supply monitoring and control circuits
• Battery-powered equipment needing low quiescent current operation
• Process control instrumentation and test equipment

Procurement Notes

Verify the specific suffix 'CKT' against the official datasheet to confirm reel quantity and tape specifications. Ensure the order matches the required accuracy grade (C Grade) and temperature range (-40°C to +85°C). Cross-reference the manufacturer part number with authorized distributors to confirm RoHS compliance and availability status before finalizing procurement.

Selection Notes

Select this component when an adjustable reference voltage between 1.225 V and 10 V is required in a compact SC-70-5 footprint. It is suitable for designs prioritizing low power consumption with a minimum operating current of 45 µA. Choose this variant over fixed-output models if circuit flexibility allows for external resistor divider configuration to set the exact reference potential.

Part Context

This device belongs to the LM4041-N series of precision micropower shunt voltage references. The series offers multiple accuracy grades and packages, including SOT-23 and TO-92. The LM4041CIDCKT specifically utilizes the SC-70-5 form factor, providing a balance between small size and thermal performance for industrial and commercial applications.

Replacement Considerations

Compatible substitutes include LM4041CIM7ADJ/NOPB and LM4041DIM7ADJ/NOPB. Verify that alternative parts match the SC-70-5 package, ±0.5% accuracy, and -40°C to +85°C operating temperature range. Ensure pinout compatibility and similar electrical characteristics such as maximum cathode current and temperature coefficient.
