Overview
The LM4041CEM3-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 ±0.5% and a temperature coefficient of 100 ppm/°C. It operates with a minimum current of 45µA (typical) and supports a maximum shunt current of 12mA. The component functions within an extended industrial temperature range of -40°C to +125°C and utilizes a compact SOT-23-3 surface-mount package.
Feature Summary
- Adjustable output voltage configuration using external resistor dividers
- Stable operation across all capacitive loads without requiring output capacitors
- Low dynamic impedance and low noise characteristics for precision applications
Applications
- Data acquisition systems
- Portable battery-powered equipment
- Precision audio circuits
- Process control instrumentation
Procurement Notes
Verify the specific suffix 'CEM3' indicates the SOT-23-3 package and '-ADJ' confirms the adjustable variant. Confirm the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure correct grading and temperature rating specifications before procurement.
Selection Notes
Select this component when an adjustable reference voltage between 1.225V and 10V is required in a space-constrained design. The ±0.5% initial accuracy and 100 ppm/°C temperature coefficient make it suitable for high-precision analog signal conditioning. Ensure the application can provide the minimum operating current of 45µA while staying within the 12mA maximum shunt current limit for stable regulation.
Part Context
This part belongs to the LM4041 family of precision micropower shunt voltage references. The family includes fixed voltage options and various accuracy grades (A, B, C, D). The LM4041 series is designed for portable applications due to its low power consumption and small footprint options, including SC-70 and SOT-23 packages, providing flexibility for cost-sensitive and size-restricted designs.
Replacement Considerations
LM4041CIM3-ADJ/NOPB: Same family member with potentially different initial accuracy grade or manufacturing lot variations but identical functional parameters.
