LM4041DIM7X-ADJ/NOPB

Voltage Reference Overview

The LM4041DIM7X-ADJ/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It features an adjustable output voltage range from 1.225V to 10V, set via external resistors. The device offers an initial accuracy of 1% and a temperature coefficient of 150 ppm/°C. It operates within a wide current range of 45µA (typical) to 12mA and maintains stability with any capacitive load without requiring output capacitors. The component is housed in a compact SC-70-5 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.

Voltage Reference Feature Summary

• Adjustable output voltage capability ranging from 1.225V to 10V using external resistor dividers
• Stable operation with all capacitive loads without the need for additional output capacitors
• Low dynamic impedance and low noise characteristics for precise reference applications
• Micropower consumption suitable for battery-powered portable devices

Voltage Reference Applications

• Data acquisition systems requiring stable reference voltages
• Portable and battery-powered equipment where power efficiency is critical
• Process control instrumentation and test equipment
• Precision audio circuits demanding low noise performance

Voltage Reference Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration when ordering. Confirm that the 'ADJ' designation matches the requirement for an adjustable output rather than a fixed voltage variant. Ensure the SC-70-5 package footprint aligns with the target PCB layout. Check RoHS compliance status as indicated by the NOPB suffix for environmental regulatory adherence.

Voltage Reference Selection Notes

Select this component when an adjustable reference voltage between 1.225V and 10V is required in a small surface-mount package. It is appropriate for designs needing 1% initial accuracy and operation up to 125°C. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements. This part is suitable for space-constrained applications where external capacitors must be avoided for stability.

Voltage Reference Part Context

This device belongs to the LM4041 family of precision micropower shunt voltage references from Texas Instruments. The family includes fixed and adjustable variants in various packages such as SOT-23, SC-70, and TO-92. The LM4041 series utilizes Zener-zap trimming for tight tolerance control across different grades, offering flexibility in cost and performance selection for general-purpose voltage reference applications.
