Procurement Notes

Verify the manufacturer marking and date code against official Linear Technology (Analog Devices) records. Confirm the suffix 'IR' indicates the industrial temperature range specification. Request original manufacturer documentation to validate authenticity and traceability before integration into critical systems.

Selection Notes

Select this component when a differential output with controlled common-mode voltage is required. Compare bandwidth and noise specifications against alternative video amplifiers. Ensure the supply voltage range aligns with the system's power architecture. Consider thermal dissipation requirements based on the load impedance and operating ambient temperature.

Part Context

This part belongs to the family of high-performance video amplifiers designed for professional broadcast and medical imaging applications. It addresses the need for precise signal handling in environments where signal distortion must be minimized. The device integrates functions typically requiring multiple discrete components, reducing board space and design complexity.

Replacement Considerations

Consult Analog Devices official substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Generic video amplifiers may not match the specific noise or bandwidth performance required for professional video applications.
