Procurement Notes

Verify the specific suffix 'ADZ' against official Analog Devices documentation to confirm compliance status and material composition. Confirm that the 18-pin SBCDIP package matches the required footprint for the target PCB design. Ensure the selected variant meets the necessary thermal and electrical specifications for the intended operational environment before finalizing procurement.

Selection Notes

Select this component when two-quadrant analog computation is required in a through-hole assembly. The 400 kHz bandwidth suits moderate-speed signal processing tasks. Verify that the ±4.5V minimum supply voltage aligns with the system power architecture. Consider the physical dimensions of the 18-pin DIP package during layout planning to ensure adequate clearance on the printed circuit board.

Part Context

This part belongs to the AD538 series of special purpose amplifiers designed for analog computation. It serves as a dedicated solution for implementing mathematical operations directly on continuous signals. The series provides a robust alternative to discrete transistor-based multiplier designs, offering improved accuracy and simplified integration into analog signal chains requiring precise scaling or division functions.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when evaluating alternatives.
