Overview
The CLC446AJ-QML is a high-speed, single operational amplifier manufactured by National Semiconductor. It is designed for demanding analog applications requiring fast transient response and wide bandwidth. The device features a JANTXV grade qualification, ensuring reliability in harsh environments. It utilizes a hermetic ceramic dual in-line package (CDIP-8) to provide superior thermal and mechanical stability compared to standard plastic packages. This component serves as a robust solution for precision signal conditioning where long-term drift and environmental resistance are critical factors.
Feature Summary
- Hermetically sealed ceramic construction for enhanced environmental protection
- JANTXV grade qualification for military and aerospace reliability standards
- High slew rate capability for rapid signal processing
- Wide bandwidth operation suitable for high-frequency applications
Applications
- Military radar systems
- Aerospace avionics
- Satellite communication equipment
Procurement Notes
Verify the specific suffix codes against the manufacturer's current datasheet to ensure compatibility with JANTXV requirements. Confirm that the CDIP-8 package dimensions match the target PCB footprint. Check for any recent obsolescence notices or lifecycle status updates from Texas Instruments, which acquired National Semiconductor. Ensure proper handling procedures for hermetic ceramic packages during assembly.
Selection Notes
Select this component when radiation hardness and hermetic sealing are mandatory. Compare performance metrics such as slew rate and gain-bandwidth product against other JANTXV amplifiers if alternative sources are considered. Evaluate thermal management needs due to the ceramic package characteristics. Consider cost implications associated with military-grade qualification versus commercial alternatives.
Part Context
This part belongs to the CLC446 family of high-speed operational amplifiers originally developed by Comlinear and later supported by National Semiconductor. The QML designation indicates adherence to strict quality assurance levels required for defense and space applications. The family is known for its ability to drive heavy capacitive loads while maintaining stability.
Replacement Considerations
Direct replacements must match the JANTXV qualification and CDIP-8 package. Verify pinout compatibility before substitution. Cross-reference with other JANTXV op-amps offering similar bandwidth and slew rate specifications.
