ADSP-1009AKG - 12x12 Multiplier Accumulator | Analog Devices
部品番号: ADSP-1009AKG ✗ 生産終了ADSP-1009AKG 概要
A multiplier/accumulator is a digital signal-processing building block that multiplies two numerical operands and adds the result to an accumulator. This function belongs to the DSP peripheral hierarchy, which includes multiplier-accumulators, correlators, FIR filters, FFT processors, and other fixed-point arithmetic engines. It is especially useful when a system must perform repeated multiplication, summation, correlation, or weighted signal accumulation without implementing those operations entirely in general-purpose logic.
The ADSP-1009AKG's principal verified characteristics include a 12 x 12 multiplier, 27-bit output bus, 5 V power supply, 5.25 V maximum supply voltage, and 68-pin PGA package. Its commercial temperature grade and pin-grid package distinguish it from many modern surface-mount DSP peripherals. The package is larger than typical QFN or BGA packages, but it offers a straightforward socket-compatible or through-hole assembly option when the original circuit board mechanically supports PGA devices.
The arithmetic architecture is intended to reduce the number of sequential multiply-and-add operations required by DSP filters and related algorithms. Designers can use the accumulator path when calculating terms such as y[n] = x[n]h[n] + y[n-1], where each new product is accumulated with a previous state value. The provided sources do not disclose clock frequency, throughput, latency, resolution beyond the stated output bus, or accumulator width, so those values must be confirmed in the manufacturer documentation before timing-critical implementation.
Typical legacy applications include digital filtering, signal correlation, modulation and demodulation support, measurement systems, and industrial DSP modules. The ADSP-1009AKG is most appropriate when an existing board requires the original PGA footprint and the design can satisfy the device's 5 V supply requirements. Modern designs may instead favor a system-on-chip DSP because such devices integrate memory, peripherals, and multiple arithmetic engines in a smaller package.
For a new PCB, preserve the full 68-terminal PGA footprint, verify every signal assignment against the manufacturer pinout, and provide regulated 5 V power with appropriate decoupling. Do not substitute a functionally similar multiplier unless its package, pinout, logic levels, timing, and numeric behavior have all been independently verified. Replacement risk is particularly high because the supplied web results provide only limited device-level technical data.
This page consolidates verified distributor pricing, package information, power limits, and bus information into a design-focused reference. It also separates confirmed specifications from unknown timing and lifecycle details, making it possible to identify what an engineer must still verify in the Analog Devices datasheet before schematic capture, layout release, or production sourcing.

主な用途
ADSP-1009AKG の用途: 6 件s: Digital Filter Processing, Signal Correlation, Industrial Measurement Systems, Modulation and Demodulation, Legacy DSP Board Maintenance, Instrumentation and Control Loops.
Digital Filter Processing
The ADSP-1009AKG is suited to legacy digital-filter datapaths that repeatedly form weighted products and accumulate the results. Its verified 12 x 12 multiplier provides the product stage, while the accumulator path can support operations equivalent to y[n] = x[n]h[n] + y[n-1]. In a filter implementation, the device can operate beside a processor or FPGA that supplies coefficients, clocks, and control signals. The confirmed 27-bit output bus provides a defined data path to that controller. Before circuit release, engineers must verify accumulator width, pipeline latency, clock rate, and output timing from the manufacturer datasheet because those values are absent from the supplied listings.
おすすめ
Signal Correlation
Correlation systems commonly require a sequence of multiply-and-accumulate operations, making the ADSP-1009AKG a relevant arithmetic building block for legacy DSP hardware. Its verified 12 x 12 multiplier and 27-bit output bus can fit between sampled input data and a downstream processor, provided that the exact numeric range and accumulation behavior match the algorithm. The PGA-68 package makes the device especially practical when repairing or reproducing a wired legacy board. Engineers should validate signed-data handling, rounding, overflow, reset behavior, and maximum throughput before committing a replacement to production, because the available sources do not expose those implementation details.
おすすめ
Industrial Measurement Systems
The ADSP-1009AKG can serve as a fixed-point arithmetic element in legacy industrial measurement equipment that computes products of sampled and reference values before summation or threshold evaluation. Its nominal 5 V supply and 5.25 V maximum rating fit systems designed around regulated 5 V rails, while the commercial temperature grade must be checked against the actual enclosure environment. The 68-pin PGA footprint is mechanically convenient for through-hole service panels and older controller boards. A successful design still requires grounding and decoupling review, input scaling, protection decisions, and confirmation that the device's numeric behavior satisfies the instrument's accuracy and safety requirements.
おすすめ
Modulation and Demodulation
A fixed-point multiplier/accumulator is useful in modulation and demodulation architectures that combine a signal with a local carrier or coefficient sequence. The ADSP-1009AKG's 12 x 12 multiplier can implement the product term in such a datapath, with the 27-bit output bus carrying the result to a processor or controller. The commercial-grade PGA-68 device may fit legacy communications equipment where the board already provides the mechanical footprint and 5 V rail. Integration requires verification of signed arithmetic, rounding, saturation behavior, clock timing, and throughput. These unresolved parameters make the ADSP-1009AKG more appropriate for maintenance and controlled reuse than for an unconstrained new design.
おすすめ
Legacy DSP Board Maintenance
ADSP-1009AKG is most directly applicable to the repair or continuation of a legacy DSP board that already uses a 68-terminal PGA multiplier/accumulator. The confirmed 12 x 12 arithmetic capability, 27-bit output bus, and nominal 5 V operation allow a replacement to preserve the board's original architecture without redesigning the arithmetic section. Because the package uses a 2.54 mm pin pitch, socket availability and mechanical alignment become important procurement considerations. A repair should not be based on function alone: compare the manufacturer pinout, power requirements, control levels, timing, and numeric behavior, and inspect the device for damage before placing it in equipment with potentially high-value downstream circuitry.
おすすめ
Instrumentation and Control Loops
The ADSP-1009AKG can support legacy control and instrumentation systems that calculate products between measured variables and weighting coefficients before accumulating a command or correction value. Its dedicated multiplier/accumulator function can reduce the arithmetic workload presented to a supervising processor, while the 27-bit output bus provides a defined connection between those blocks. The PGA-68 package and 5 V supply are compatible with older wired control architectures, although thermal and environmental limits are not supplied. Engineers should verify signal settling requirements, control-loop latency, overflow handling, and power sequencing before deployment, particularly where an incorrect numeric implementation could create unsafe control behavior.

設計ノート
Design the ADSP-1009AKG around a tightly regulated 5 V rail because the verified maximum supply voltage is only 5.25 V. Place the required local bypass capacitors at the supply and ground pins according to the manufacturer layout guidance, and keep switching-converter routing away from the device. The supplied records do not specify supply current, ripple tolerance, or sequencing, so those values must be confirmed before selecting capacitors or setting the power-source tolerance. Estimated current calculations are not possible without the unavailable operating-frequency and power-consumption data.
Preserve the complete 68-terminal PGA footprint, including its 2.54 mm pitch and the verified square package orientation. Confirm pin 1, every signal assignment, and thermal or socket requirements from the official package drawing rather than inferring them from board artwork. PGA packages are mechanically sensitive to alignment and insertion force, so new boards should include adequate keep-out clearance and accessible inspection points. If this component replaces a socketed device, verify socket pin length, contact plating, and component seating height to avoid incompatible mechanical stackups.
Do not assume that every same-family ADSP-1009 ordering code has an interchangeable pinout. Before substituting a candidate, compare control signals, data bus width, clock-edge behavior, numeric overflow handling, reset polarity, and output timing from the manufacturer documentation. A PGA package with the same terminal count can still be incompatible if its terminal functions differ. For a production migration, perform a documented pin-by-pin comparison and validate the candidate in the original system, including known input vectors and boundary conditions.
The marketplace label describing a 12 x 12 multiplier does not establish the complete accumulator width, numerical format, or throughput of the ADSP-1009AKG. These omissions can lead to incorrect filter and correlation implementations even when a replacement appears electrically compatible. Obtain the exact manufacturer datasheet, verify signed versus unsigned operation, rounding, saturation, pipeline latency, clock maximum, and output valid timing, and use boundary-value vectors during qualification. Do not treat the 27-bit output bus as proof of a 27-bit internal accumulator.
