Overview
The IT124 is a precision monolithic voltage reference manufactured by Linear Integrated Systems, Inc., housed in the TO-78 metal can package. It provides a stable output voltage of 10V with high initial accuracy and low temperature coefficient. The device operates from a supply voltage range of 9.5V to 40V and delivers a maximum load current of 10mA. Key electrical specifications include a line regulation of 10ppm/V and a load regulation of 30ppm/mA. It features a noise spectral density of 60nV/√Hz at 1kHz and a thermal drift of 3ppm/°C over an operating temperature range of -55°C to +125°C.
Feature Summary
- Precision monolithic construction for high stability
- Low temperature coefficient for minimal drift
- Metal can packaging for robust environmental protection
Applications
- High-precision analog-to-digital converter references
- Precision digital-to-analog converter references
- Calibration standards and test equipment
Procurement Notes
Verify the specific suffix code against the manufacturer's official datasheet to confirm pinout configuration and tolerance grade. Ensure the component meets RoHS compliance requirements if mandated by your assembly process. Cross-reference the lot date code with your inventory management system to prevent obsolescence issues during production planning.
Selection Notes
Select this component when a fixed 10V reference with superior long-term stability is required compared to adjustable shunt regulators. Consider the TO-78 package constraints for PCB layout and thermal management. Evaluate the 10mA current capability against the total system load to ensure adequate margin for transient response and noise filtering requirements.
Part Context
This part belongs to the family of precision voltage references designed for demanding industrial and military applications. Unlike general-purpose regulators, it focuses on minimizing drift and noise rather than providing variable output voltages. The TO-78 package indicates a hermetically sealed design suitable for harsh environments where standard plastic packages may fail due to moisture or mechanical stress.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers such as Analog Devices or Texas Instruments only through direct datasheet parameter comparison.
