ADSP-1080AJN - 8-Bit CMOS DSP Multiplier | Analog Devices
MPN: ADSP-1080AJN ✗ Tapus ng BuhayADSP-1080AJN Ulas
A DSP multiplier is a specialized digital arithmetic circuit that computes the product of two binary numbers. It belongs to the digital signal processing multiplier hierarchy, where it operates as a dedicated arithmetic accelerator rather than a general-purpose microprocessor. Such multipliers can implement convolution, correlation, scaling, FIR-filter coefficient processing, and mixed-signal control calculations when combined with external adders, registers, memory, and interface logic.
The ADSP-1080AJN provides 8-bit multiplier capability and 8 x 8 multiplication in a 40-pin PDIP package. Its through-hole terminal arrangement supports conventional PCB sockets and prototype boards, while the plastic PDIP40 package provides a 0.600-inch, 15.24 mm lead pitch according to the Rochester Electronics product listing. The commercial temperature grade, CMOS construction, and through-hole termination identify the part as a legacy DIP-era DSP building block.
Because the supplied web evidence identifies the device under Analog Multipliers and Dividers as well as DSP Peripheral, it is suitable for signal-chain arithmetic, digital filtering, and DSP subsystem designs where an external processor requires a dedicated multiplication path. The DIP package also makes the component practical for educational DSP platforms, laboratory instrumentation, and maintenance of older equipment, although modern mixed-signal and FPGA designs generally favor newer, smaller, mixed-signal and FPGA designs generally favor newer, smaller, higher-speed devices.
Engineers should preserve the original supply configuration because DIP packages, inter-pitch, and older Ceramic DIP package outlines remain difficult to source in volume. Rochester Electronics lists the ADSP-1080AJN as original manufacturer-standard stock, with pricing beginning at $121.88 per unit as of October 29, 2026. Availability, operating-temperature limits, supply voltage, clock rate, and individual pin functions were not included in the supplied data and must be confirmed against the manufacturer datasheet before design release.
The key design consideration is that a multiplier alone does not create a complete digital filter. Clocking, output registers, truncation behavior, propagation delay, and interface logic must be evaluated in the wider DSP architecture. This page combines verified package and pricing information, available same-family alternatives, and practical sourcing guidance for engineers maintaining legacy DSP systems rather than reproducing unverified timing or electrical limits.

Tipikal na mga Gamit
ADSP-1080AJN ay nararapat para sa 6 aplikasyons: Legacy FIR Filter Design, Digital Correlation and Convolution, Digital Control System Scaling, DSP Education and Prototyping, Legacy Audio and Control Signal Processing, Maintenance of DIP-40 DSP Peripherals.
Legacy FIR Filter Design
The ADSP-1080AJN is appropriate as the dedicated multiplication stage of an externally implemented FIR filter because it provides an 8 x 8 CMOS multiplication function in a 40-pin PDIP package. A practical implementation routes 8-bit coefficient and sample values into the multiplier, latches the 16-bit product, and connects the result to an accumulator formed from external adders. The through-hole package simplifies laboratory construction and socketed maintenance of older filter boards. However, the supplied evidence does not state clock rate, propagation delay, or power consumption, so filter throughput must be calculated from the manufacturer timing data rather than assumed.
Inirekomenda
Digital Correlation and Convolution
An 8 x 8 CMOS multiplier is directly useful in correlation, convolution, and matched-filter architectures where sampled sequences are multiplied by stored coefficients. The ADSP-1080AJN can serve this arithmetic role in a laboratory DSP trainer or an industrial controller that retains a through-hole DSP peripheral board. Because the device is documented as an 8-bit multiplier, 40-terminal PDIP part, the system designer must add the required sequencing registers and accumulation path externally. Verify timing and output-word behavior from the datasheet, as those electrical details were not included in the supplied verified results.
Inirekomenda
Digital Control System Scaling
The ADSP-1080AJN can be used to scale an 8-bit control variable by an 8-bit coefficient inside a legacy digital control loop. This is useful when an existing controller already uses external bus logic but lacks a dedicated multiplier. The 40-pin PDIP arrangement makes retrofit and educational work straightforward, while the commercial-grade designation supports non-automotive laboratory and industrial maintenance use when its specified temperature limits are confirmed. Designers should budget external latching to hold operands during multiplication and verify rounding and truncation behavior directly against the manufacturer documentation.
Inirekomenda
DSP Education and Prototyping
The ADSP-1080AJN is well suited to a laboratory demonstration or teaching board that exposes the internal stages of digital multiplication. Its 8-bit resolution and 8 x 8 CMOS architecture make the arithmetic behavior easy to illustrate with switch-selectable operands, LEDs, counters, and external registers. The PDIP-40 package also allows students or technicians to socket the device instead of attaching it directly to a compact board. The main limitation is sourcing continuity rather than educational value; verify the price and authenticity with a specialist distributor before building multiple training stations.
Inirekomenda
Legacy Audio and Control Signal Processing
In an older audio or industrial control system, the ADSP-1080AJN can implement gain, scaling, and coefficient multiplication stages within a broader DSP peripheral network. Its CMOS construction and 8-bit arithmetic align with legacy digital signal-processing boards that process control words rather than high-resolution audio streams. The 40-pin through-hole package eases socketed replacement during maintenance. Designers should not assume modern audio performance: the supplied data does not identify noise, distortion, bandwidth, or output-drive specifications, so those requirements must be validated against the original ADSP-1080 datasheet.
Inirekomenda
Maintenance of DIP-40 DSP Peripherals
The ADSP-1080AJN is most valuable as a maintenance component for an existing board that uses a 40-pin DIP DSP multiplier. Its through-hole PDIP construction and 0.600-inch, 15.24 mm lead pitch allow it to replace a failed original device when the board has a socket and the correct device suffix has been verified. Rochester Electronics identifies original manufacturer-standard stock, which supports this repair use case. Before installation, compare the suffix-specific temperature grade and electrical limits and check every pin against the manufacturer datasheet, since the individual pinout was not supplied in the search results.

Talaan ng Disenyo
Do not substitute an ADSP-1080 suffix solely because the multiplier and package names match. The J, K, and D characters can identify different ordering, temperature, or qualification arrangements. Confirm the complete manufacturer pinout, supply voltage, timing, and temperature limits for both the installed device and the proposed replacement. The supplied comparison data supports ADSP-1080AKN and ADSP-1080AKD as same-family candidates, but it does not include the suffix-specific electrical tables needed for unconditional approval.
Preserve the original 0.600-inch, 15.24 mm DIP grid and route all 40 signals to a socket or plated through-holes when creating a replacement board. Provide short, quiet connections for operand and product buses, and keep clock and control traces away from sensitive analog inputs. Because the DIP package exposes long leads, decouple the power pins close to the device with a local bypass capacitor and follow the manufacturer recommendation for its value and voltage rating.
Estimate the board's supply demand before adding a replacement multiplier by accounting for the device's own current consumption and any newly added external logic. The supplied web results do not include supply-voltage or quiescent-current ratings, so a numerical power budget cannot be produced from the available evidence. Use the manufacturer datasheet for current, absolute maximum voltage, and decoupling requirements, then verify the source rail has adequate startup margin and transient response.
Impormasyon ng Pagsunod sa Kautusan
The supplied web data identifies a commercial-grade legacy PDIP device but contains no RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not applicable because the product is not identified as an automotive-qualified device in the supplied evidence.
