Voltage Reference datasheet and documents for LM4041D12QDBZR
Voltage Reference Overview
The LM4041D12QDBZR is a precision micropower shunt voltage reference from Texas Instruments, offering a fixed output of 1.225V with 1% initial accuracy. It operates within an extended temperature range of -40°C to +125°C and features a low temperature coefficient of 150 ppm/°C. The device supports a maximum cathode current of 12mA and maintains stability across all capacitive loads without requiring external output capacitors. Packaged in a compact SOT-23-3 surface-mount format, it is designed for space-constrained applications.
Voltage Reference Feature Summary
- Provides stable voltage reference performance across wide capacitive loads without requiring external output capacitors
- Utilizes Zener-zap reverse breakdown voltage trimming for precise initial accuracy and low temperature coefficient
- Designed for micropower operation with minimum operating current as low as 45µA typical
Voltage Reference Applications
- Data acquisition systems
- Power supply monitoring circuits
- Industrial process control instrumentation
- Automotive electronics
- Battery-powered portable devices
Voltage Reference Procurement Notes
Verify the specific suffix 'Q' indicates automotive qualification compliance per official documentation. Confirm the package marking code matches the D12 variant specifications. Ensure the ordering part number aligns with the required temperature grade and accuracy class for the target application environment.
Voltage Reference Selection Notes
Select this component when a fixed 1.225V reference is required in an SOT-23-3 package. Choose the Q-grade variant specifically for applications demanding operation up to 125°C. Consider the 1% accuracy tolerance against system requirements before opting for higher precision A or B grades.
Voltage Reference Part Context
This part belongs to the LM4041 family of precision shunt voltage references. The family includes adjustable versions and various accuracy grades (A, B, C, D). The LM4041xQ series specifically targets extended temperature ranges suitable for industrial and automotive environments compared to standard industrial grade parts.
Voltage Reference Replacement Considerations
LM4041D12IDBZR offers identical electrical characteristics but lacks automotive qualification. LM4040 series provides similar functionality in different packages. Verify pinout compatibility and thermal performance when substituting.
