ADSP-1080AKN - 8-Bit CMOS DSP Multiplier | Analog Devices
MPN: ADSP-1080AKN ✗ Cuối đờiADSP-1080AKN Tóm tắt
An 8-bit DSP multiplier is a specialized arithmetic block that multiplies two 8-bit operands and produces a wider numerical result. This makes the ADSP-1080AKN part of the broader DSP peripheral hierarchy, where multiplication and division support signal-processing, filtering, scaling, and other fixed-point arithmetic functions. Its legacy PDIP40 package favors through-hole construction and applications in older or long-lifecycle electronic systems rather than compact surface-mount products.
The ADSP-1080AKN combines an 8-bit multiplier with CMOS technology in a 40-pin PDIP40 package. The supplied product records identify it as a DSP peripheral with through-hole terminals and a rectangular package shape. A distributor price of $24.94 is available as of 2026-10-30. Its commercial temperature grade distinguishes it from military- and industrial-temperature versions of the same family.
The through-hole PDIP40 construction provides 40 physical connection points and suits legacy controller, signal-processing, and instrumentation boards. CMOS implementation is specifically identified in the verified product records. No verified timing frequency, supply voltage, accuracy, multiplier propagation delay, power dissipation, or operating-temperature values were supplied, so those electrical parameters remain unknown rather than being estimated.
Typical engineering uses include 8-bit digital signal-multiplication stages, embedded arithmetic interfaces, educational DSP platforms, and maintenance of legacy equipment. In these contexts, the ADSP-1080AKN serves as a dedicated arithmetic peripheral rather than a general-purpose microprocessor. System designers should verify the complete datasheet signal definitions, supply requirements, and timing behavior before creating a new production design.
A key design consideration is availability and lifecycle risk. Although the Dasenic listing describes ADSP-1080AKN as in stock, Rochester Electronics is the source of the verified marketplace entry, and the family is identified as obsolete. New deployments should therefore confirm authorized sourcing, traceability, and long-term supply, while existing installations should avoid schematic or footprint changes unless the replacement is independently qualified.
This page combines verified distributor availability, package information, pricing, lifecycle evidence, and a qualified same-family comparison with practical sourcing guidance. It distinguishes documented facts from missing technical data and avoids treating general cross-reference search results as proof of pin-to-pin replacement without package-level verification.

Ứng dụng tiêu biểu
ADSP-1080AKN phù hợp cho 6 Áp dụngs: Legacy 8-Bit DSP Arithmetic, Embedded Signal-Processing Controller, Digital Filter and Scaling, Instrumentation Control and Measurement, Educational DSP Platforms, Obsolete Equipment Sustaining.
Legacy 8-Bit DSP Arithmetic
The ADSP-1080AKN fits legacy systems that require a dedicated 8-bit CMOS multiplier rather than software-based arithmetic. Its verified DSP-peripheral classification and multiplier/divider function place it directly in the arithmetic path of an older digital signal-processing design. The 40-pin PDIP40 package is appropriate for boards designed around through-hole assembly. Before integrating it into a new design, engineers must retrieve the manufacturer datasheet to verify supply voltage, clocking, result width, throughput, and output timing.
Được đề xuất
Embedded Signal-Processing Controller
The ADSP-1080AKN can support an embedded signal-processing controller that delegates multiplication to a dedicated DSP peripheral. Its documented 8-bit multiplier function is relevant to scaling, filtering, and fixed-point arithmetic in legacy control equipment. The commercial temperature grade and commercial-tier designation align it with ordinary commercial environments, although an exact numerical operating range was not supplied. Confirm electrical timing and interface levels against the official documentation before replacing or populating this position.
Được đề xuất
Digital Filter and Scaling
The ADSP-1080AKN is applicable to legacy digital filtering and signal-scaling blocks where an 8-bit multiplier can implement coefficient multiplication. Using the dedicated CMOS multiplier can reduce the arithmetic burden placed on a host processor while preserving an established through-hole board architecture. The supplied evidence confirms the 8-bit CMOS multiplier/divider function but does not document coefficient formats, rounding behavior, or throughput. Those details must be checked in the manufacturer datasheet before timing closure.
Được đề xuất
Instrumentation Control and Measurement
The ADSP-1080AKN can be used in legacy instrumentation and measurement equipment that computes scaled digital values through a dedicated 8-bit multiplier. Its commercial grade, rectangular PDIP40 package, and through-hole terminals fit older instrument-control boards designed for serviceable through-hole construction. Because verified sources do not disclose analog signal conditioning, clock frequency, or accuracy, the part should be treated strictly as a digital arithmetic block rather than a complete measurement front end.
Được đề xuất
Educational DSP Platforms
The ADSP-1080AKN suits educational DSP platforms intended to demonstrate multiplication, scaling, and processor-peripheral interfacing with an 8-bit CMOS device. Its 40-pin through-hole package makes it practical for solderless or manually assembled training boards. The verified listing supports the component identity, resolution, CMOS technology, and package format, but it does not provide a complete lab circuit or pinout. Instructors should use the official datasheet and verify the obsolete lifecycle status before designing coursework around it.
Được đề xuất
Obsolete Equipment Sustaining
The ADSP-1080AKN is especially relevant to sustaining obsolete equipment where an existing board requires a plastic PDIP40 8-bit CMOS multiplier. Verified marketplace records show stock availability, and the distributor price is $24.94 USD as of 2026-10-30, but the family is identified as obsolete. Maintenance teams should document the manufacturer, date code, condition, and inspection results for every installed part, and should avoid assuming that a related ceramic package is mechanically interchangeable.

Ghi chú thiết kế
Do not treat every 40-pin ADSP-1080 member as mechanically interchangeable. The verified ADSP-1080AKD is a ceramic CDIP40 device, whereas the ADSP-1080AKN uses a plastic PDIP40 package. Socketed legacy boards may tolerate selected substitutions, but soldered assemblies require a mechanical drawing, pin-layout comparison, thermal review, and operating-grade verification. The ADSP-1080AJN is the only related candidate supported by the provided comparison data as having the same PDIP40 package classification.
Supply-voltage and current information is absent from the verified records, so the ADSP-1080AKN must not be connected to a legacy rail based on inference. Obtain the official manufacturer datasheet, confirm the device suffix, and verify power and ground pin assignments before energizing the board. Inspect for socket corrosion and socketed-part oxidation during obsolete-equipment maintenance, because poor electrical contact can resemble a defective multiplier.
Preserve the original PDIP40 footprint, pin numbering, and component orientation when replacing an ADSP-1080AKN. Check pin 1 against the board's documented orientation rather than relying only on visual proximity, particularly in crowded through-hole designs. The supplied data does not include a manufacturer pinout, so no individual signal assignment should be inferred. Capture a continuity check and verify unused and no-connect positions against the official documentation before returning equipment to service.
The ADSP-1080AKN is a legacy through-hole digital IC, but no verified power dissipation or thermal-resistance values are available. Do not infer acceptable self-heating from the commercial-grade designation or the 40-pin package alone. For a new assembly, derive worst-case dissipation from manufacturer supply-current and operating-frequency limits after obtaining the datasheet, then account for socket, airflow, board copper, and nearby heat sources. Existing equipment should be inspected for discoloration, cracking, or socket deterioration.
Thông tin tuân thủ
