AD533LD

Overview

The AD533LD is a low-cost integrated circuit multiplier manufactured by Analog Devices. It comprises a transconductance multiplying element, a stable reference, and an output amplifier. The device operates as a four-quadrant analog multiplier or divider. It is housed in a 14-lead Ceramic Dual In-Line Package (CDIP) with a window, suitable for hermetic sealing. The component is classified as obsolete.

Feature Summary

• Four-quadrant analog multiplication and division capability
• Integrated stable voltage reference
• Built-in output amplifier stage

Applications

• Analog signal processing requiring precise multiplication
• Frequency mixing applications
• Automatic gain control circuits

Procurement Notes

Verify obsolescence status before design finalization. Confirm package compatibility for legacy systems requiring ceramic DIP housing. Source only from authorized distributors handling obsolete stock to ensure authenticity and traceability.

Selection Notes

Select this component for applications requiring hermetically sealed analog multipliers. Ensure the system design accommodates the CDIP-14 windowed package constraints. Verify that the obsolete status aligns with long-term availability requirements.

Part Context

The AD533 series represents Analog Devices' legacy analog computing components. The LD suffix denotes the ceramic dual in-line package variant. This family provides high-precision multiplication functions using transconductance technology, distinct from modern digital alternatives.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Evaluate modern analog multipliers such as the AD633 or AD734 for functional equivalence, noting differences in packaging and interface.
