LM4041CIM7X-ADJ/NOPB

Overview

The LM4041CIM7X-ADJ/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It features an adjustable output voltage range from 1.225 V to 10 V, set via external resistors. The device offers an initial accuracy of ±0.5% and a temperature coefficient of 150 ppm/°C. It operates within a maximum shunt current of 12 mA and supports a wide operating temperature range from -40°C to +125°C. Packaged in the SC-70-5 surface-mount format, it ensures stability with any capacitive load without requiring an external stabilizing capacitor.

Feature Summary

• Adjustable output voltage configuration using external resistor dividers
• Stable operation with any capacitive load without external compensation
• Precision trimming for tight initial accuracy tolerance
• Micropower design suitable for battery-powered applications

Applications

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

Procurement Notes

Verify the specific suffix 'CIM7X' corresponds to the SC-70-5 package and industrial temperature grade when sourcing. Confirm the 'ADJ' designation indicates the adjustable variant rather than fixed voltage options. Ensure compatibility with standard SC-70 footprints during PCB layout. Check RoHS compliance status as indicated by the NOPB suffix. Validate that the supplier provides genuine Texas Instruments components to guarantee specified electrical performance.

Selection Notes

Select this component when an adjustable reference voltage between 1.225 V and 10 V is required in a compact form factor. It is appropriate for designs needing ±0.5% accuracy at 25°C. Consider the 150 ppm/°C drift if high thermal stability across extreme temperatures is critical. Compare against fixed voltage variants if the application does not require adjustability. Evaluate the 12 mA maximum current limit against load requirements.

Part Context

This part belongs to the LM4041-N family of precision voltage references. The series includes fixed voltage options and various accuracy grades (A, B, C, D). The CIM7X variant specifically denotes the adjustable version in the SC-70-5 package with extended temperature capabilities compared to standard industrial grades.

Replacement Considerations

LM4041DIM7X-ADJ/NOPB: Different accuracy grade (±1%). LM4041BIM7X-ADJ/NOPB: Higher accuracy grade (±0.2%). LM4041AIM7X-ADJ/NOPB: Highest accuracy grade (±0.1%). Verify package pinout compatibility before substitution.
