ADSP-1009AKN

Overview

The ADSP-1009AKN is a high-speed analog multiplier and accumulator integrated circuit manufactured by Analog Devices Inc. It features a 12-bit by 12-bit multiplication capability with an accumulated output, designed for precise signal processing tasks. The device operates on a single 5V supply voltage and utilizes a 64-pin Dual In-Line Package (DIP). It supports an external data bus width of 12 bits and provides a 27-bit output data bus width for accumulation results. The component is rated for operation within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Performs 12-bit by 12-bit analog multiplication with internal accumulation
• Operates from a single 5V power supply
• Provides 27-bit accumulated output data path
• Housed in a standard 64-pin ceramic DIP package

Applications

• Analog signal processing systems requiring real-time multiplication
• Frequency synthesis and modulation circuits
• Automatic gain control loops
• Vector magnitude calculations

Procurement Notes

Verify the specific suffix 'KN' against the manufacturer's current datasheet to confirm pinout compatibility and material composition. Note that older components may not comply with modern RoHS directives; check regulatory status if required for your assembly process. Ensure the 64-DIP footprint matches your PCB design constraints before procurement.

Selection Notes

Select this component when a dedicated analog multiplier with accumulation is required rather than a general-purpose DSP. Consider the 64-DIP package size for through-hole mounting requirements. Verify that the 5V single-supply operation aligns with your system power architecture and that the 12-bit resolution meets your precision needs.

Part Context

The ADSP-1009 series belongs to Analog Devices' legacy line of high-performance analog multipliers. These devices were designed to provide hardware-accelerated mathematical operations for analog signals, reducing the computational load on digital processors in mixed-signal applications.

Replacement Considerations

Check for direct equivalents such as the AD633 or AD734 for simpler multiplication tasks, though these lack the built-in accumulator. For higher precision or different packaging, consult Analog Devices' current analog multiplier portfolio for updated alternatives.
