LM4041DIDCKT

Voltage Reference Overview

The LM4041DIDCKT is an adjustable precision shunt voltage reference from Texas Instruments, housed in a SC-70-5 surface-mount package. It offers an output voltage range of 1.225V to 10V with a maximum initial accuracy of 1% and a temperature coefficient of 150ppm/°C. The device operates within an extended industrial temperature range of -40°C to +125°C. It supports a wide operating current range from a typical minimum of 45μA up to 12mA. The component is stable with all capacitive loads without requiring external output capacitors.

Voltage Reference Feature Summary

• Adjustable output voltage capability ranging from 1.225V to 10V via external resistors
• Stable operation with any capacitive load without the need for output capacitors
• Low dynamic impedance and low noise characteristics for precision applications
• Extended temperature range operation suitable for demanding environments

Voltage Reference Applications

• Data acquisition systems
• Power supply monitoring circuits
• Portable battery-powered equipment
• Process control instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the 'D' grade designation corresponds to the required 1% accuracy and 150ppm/°C temperature coefficient specifications. Ensure the SC-70-5 package footprint matches the design layout. Check for RoHS compliance status as per the manufacturer's latest documentation.

Voltage Reference Selection Notes

Select this component when an adjustable reference is needed in a compact SC-70-5 package. It is suitable for designs requiring stability with capacitive loads without additional components. Consider the 1% accuracy and 150ppm/°C drift if high precision is not critical. Verify that the 45μA minimum operating current fits the power budget constraints of the application.

Voltage Reference Part Context

This part belongs to the LM4041 family of micropower shunt voltage references. The family includes fixed and adjustable versions with various accuracy grades (A, B, C, D) and packages (SOT-23, SC-70, TO-92). The LM4041 series is designed for portable applications due to its low quiescent current and small form factor options.

Voltage Reference Replacement Considerations

LM4041DIDCKR is a compatible alternative in the same SC-70-5 package with identical electrical specifications.
