ADSP-1008AJD - 8-Bit DSP Multiplier | Analog Devices
Référence : ADSP-1008AJD ✗ Fin de vieADSP-1008AJD Présentation
A digital multiplier is a combinational or sequential arithmetic circuit that multiplies two binary numbers and can accumulate the result. In the product taxonomy, the ADSP-1008AJD belongs to the multiplier-accumulator-summer function within digital signal processors and DSP peripherals. This places it between general-purpose digital logic and larger programmable DSP systems: it performs a defined arithmetic operation without requiring a separate software-controlled processor core.
The principal verified feature is an 8×8 CMOS multiplier structure. This means both multiplicand and multiplier operands are represented by eight binary bits, while the wider internal result supports the multiplier-accumulator-summer function listed for the device. The manufacturer-related distributor record classifies the part as an “8-bit DSP-multiplier accumulator/summer” and separately lists “8 X 8 CMOS multiplier” as its device description.
The ADSP-1008AJD uses a hermetically sealed, side-brazed ceramic DIP-48 package measuring 0.600 inches, or 15.24 mm, across the package width. This through-hole construction differs from modern surface-mount DSP packages and supports installation in legacy or industrial printed-circuit boards. The associated records identify the component as a DSP peripheral and analog multiplier rather than a general-purpose microprocessor.
Typical engineering use includes fixed-point multiplication, accumulator-based signal processing, industrial control arithmetic, instrumentation signal chains, and maintenance of legacy DSP boards. A system designer should confirm output timing, register behavior, supply requirements, and exact pin functions against the manufacturer datasheet before creating a new PCB because those detailed operating values are not present in the supplied verified records.
The primary design consideration is lifecycle risk. The verified GlobalSpec record lists the part status as obsolete, while the icDirectory record reported a price of $33.33 and 18,350 units in stock when retrieved. Designers should therefore qualify any replacement against pinout, logic levels, timing, and arithmetic behavior rather than relying only on the “8×8 multiplier” description.
This page consolidates verified manufacturer-associated descriptions, distributor pricing, package details, lifecycle information, and application guidance for engineers searching for the obsolete ADSP-1008AJD. It also separates documented facts from unavailable technical fields, helping procurement and design teams avoid unsupported assumptions when sourcing or repairing legacy DSP equipment.

Applications typiques
ADSP-1008AJD convient pour 6 applications: Legacy Digital Signal Processing, Industrial Control Arithmetic, Instrumentation Signal Processing, Fixed-Point Arithmetic Systems, Legacy Test and Measurement Equipment, Specialized Control and Signal-Conditioning Modules.
Legacy Digital Signal Processing
The ADSP-1008AJD is appropriate for maintaining a legacy DSP board that uses a dedicated 8×8 CMOS multiplier-accumulator-summer rather than a programmable processor. Its verified function allows arithmetic operations to be implemented as fixed hardware, which can simplify timing in an established design. The 48-CDIP footprint must match the original board, and the exact control and data-pin behavior must be confirmed from the manufacturer datasheet before installation. Because the device is obsolete and has limited availability, procurement should include an authorized or traceable source and a documented inspection plan.
Industrial Control Arithmetic
ADSP-1008AJD can support a legacy industrial control system that performs multiplication or accumulation as a dedicated arithmetic stage. The verified 8×8 CMOS multiplier structure is well matched to fixed-width binary operations, while the hermetically sealed, side-brazed ceramic package provides a mechanically robust through-hole format for legacy control boards. New industrial designs should not assume the part is suitable without checking the unavailable operating-temperature and electrical specifications. Any repair or redesign should preserve the original 48-pin footprint or use a deliberate board redesign rather than an unverified substitute.
Instrumentation Signal Processing
The ADSP-1008AJD can be considered in older instrumentation architectures where a fixed multiplier-accumulator-summer processes sampled or conditioned data before conversion, analysis, or display. Its dedicated 8-bit arithmetic function may reduce processor overhead in a proven architecture, but the supplied records do not describe clock rate, conversion latency, output coding, or control timing. Engineers must consult the applicable datasheet for those parameters. Because the part is obsolete and its lifecycle supply is limited, instrument repairs should preserve traceability and validate the multiplier exhaustively against known operating vectors.
Fixed-Point Arithmetic Systems
ADSP-1008AJD fits legacy fixed-point designs that require an 8-bit multiplier-accumulator-summer as a hardware building block. The verified function can support scaling, coefficient multiplication, and accumulation stages where the original system architecture was designed around this exact device. Modern designs should evaluate programmable DSP alternatives because a discrete obsolete multiplier offers limited upgrade flexibility. For an existing board, validate the replacement against test vectors covering signed or unsigned behavior, zero inputs, overflow conditions, and pipeline timing using the original system requirements and the manufacturer documentation.
Legacy Test and Measurement Equipment
The ADSP-1008AJD can serve as the arithmetic element in legacy oscilloscope, signal-generator, analyzer, or automated test equipment that was originally designed around an 8×8 CMOS multiplier. Its 48-pin ceramic DIP package is practical for repair of through-hole instrumentation, and the dedicated function can support repeatable fixed-width processing. The verified data does not establish modern instruments' temperature, speed, or accuracy needs, so engineers must compare the original device characteristics with the instrument specification. Repair procurement should focus on remaining stock, package condition, visual inspection, and functional verification.
Specialized Control and Signal-Conditioning Modules
ADSP-1008AJD can be used when maintaining a specialized module that depends on a dedicated CMOS multiplier-accumulator-summer for signal conditioning or control arithmetic. Its 48-CDIP format allows assembly on compatible legacy hardware, while the 8×8 configuration provides a defined datapath width for binary processing. The part should not be selected for a fresh module without reviewing its original electrical and timing documentation, because supply voltage, operating speed, and environmental limits are not included in the verified records. End users should also account for obsolete-part obsolescence, component traceability, and repair inventory planning.

- Established legacy package and package width (vs Unverified cross-package replacements)
Notes de conception
Do not install ADSP-1008AJD solely because another ADSP-1008A-family MPN appears in search results. The verified target is an obsolete 8×8 CMOS multiplier in a 48-CDIP package, while the available ADSP-1008AKD result is explicitly described as a similar listing rather than an automatic replacement. Before substitution, compare every pin, supply requirement, logic level, timing edge, output coding, and multiplier behavior against the original manufacturer documentation and the equipment schematic.
Treat the ADSP-1008AJD as a through-hole ceramic DIP rather than a surface-mount part. Verify the original board's 0.600-inch, or 15.24 mm, row spacing and pin orientation against the mechanical drawing, inspect for bent or oxidized leads, and use appropriate lead-forming rather than forcing the package into the holes. The verified package is hermetically sealed and side-brazed, so mechanical stress during soldering or rework should be minimized.
The supplied verified data does not include supply voltage, input-level tolerances, or output-drive specifications. Before energizing the device, obtain the applicable manufacturer datasheet and confirm every power and ground connection from the schematic and pinout. Do not infer operating voltages from modern DSP families or from the label '8-bit CMOS.' A wrong supply level could permanently damage an obsolete device that may be difficult to replace.
The available lifecycle and regulatory records identify ADSP-1008AJD as obsolete, RoHS non-compliant, and REACH affected. That status should trigger supplier review, traceability requests, incoming inspection, and careful documentation for maintenance use. For new commercial products, assess whether regulatory obligations and long-term supply risk justify redesigning around a currently supported component rather than adding an obsolete legacy part to a new bill of materials.
