• Low input bias current for precision buffering
• JFET input stage for high impedance isolation

Applications

• Sample-and-hold circuits
• Data acquisition systems
• Precision analog signal processing

Procurement Notes

Verify the specific suffix and revision level against official Analog Devices documentation to ensure compatibility with your design requirements. Confirm that the 20-CLCC package dimensions match your PCB footprint exactly. Check for any recent Product Change Notifications (PCNs) that may affect material composition or manufacturing location. Ensure the component meets all necessary environmental and reliability standards for your intended application environment before finalizing procurement.

Selection Notes

Select this component when high-speed voltage buffering with minimal input current draw is required. The 23 MHz gain bandwidth and 120V/µs slew rate make it suitable for dynamic signals where settling time is critical. Consider the 20-CLCC package constraints during layout. Compare performance metrics against standard op-amps if lower speed or different packaging is acceptable for cost reduction.

Part Context

This part belongs to the military-grade or high-reliability segment of Analog Devices' portfolio, indicated by the 5962 prefix. It is derived from commercial JFET op-amp designs but undergoes stricter screening and testing protocols. The memory buffer configuration optimizes it for holding voltage levels accurately during conversion cycles in mixed-signal systems.

Replacement Considerations

Direct substitutes must match the 20-CLCC package, JFET input type, and similar electrical specifications. Verify pinout compatibility carefully, as variations exist within the JFET op-amp family. Consult Analog Devices for qualified alternate parts lists to ensure functional equivalence without redesigning the circuit board.
