ADSP-1081AKD/+ - 8x8 CMOS Multiplier | Analog Devices
MPN: ADSP-1081AKD/+ ✓ פעילADSP-1081AKD/+ סקירה
A CMOS digital multiplier is a signal-processing semiconductor that accepts binary operands and computes their numerical product. In the broader component hierarchy, it belongs to the digital multiplier and arithmetic-processing category, which sits within integrated circuits and specialized DSP peripherals. The ADSP-1081AKD/+ is specifically described by distributors as an analog multiplier, divider, and DSP multiplier, reflecting its use in arithmetic and signal-processing systems.
The principal verified features are the 8-bit operand architecture, 8 x 8 multiplication capability, CMOS construction, and 40-CDIP hermetically sealed ceramic packaging. Its ceramic side-brazed DIP format provides a mechanically distinct, through-hole package rather than a surface-mount form factor. Distributor records also classify the component under Analog Multipliers, Dividers, indicating that it is intended for dedicated arithmetic functions rather than general-purpose microcontrollers.
This package format makes the ADSP-1081AKD/+ relevant to legacy and specialized equipment requiring a high-pin-count, through-hole digital multiplier. The hermetically sealed ceramic construction can support applications where environmental sealing and mechanical robustness are important. Because the supplied web records do not expose operating voltage, multiplication latency, clock rate, temperature range, or individual pin assignments, those characteristics should be confirmed in the manufacturer datasheet before new circuit designs are released.
Typical engineering uses include digital signal-processing subsystems, arithmetic logic, control systems, instrumentation, and industrial equipment that requires an 8 x 8 binary multiplication function. The dedicated multiplier may be useful when performing the multiplication directly in hardware is preferable to implementing repeated addition in a microcontroller or programmable logic device. Its 40-pin ceramic package, however, requires careful planning because through-hole ceramic devices are larger than comparable surface-mount multipliers.
The primary design consideration is verification: available distributor results identify the device and package but do not provide a complete manufacturer pinout, timing specification, or electrical limits. Engineers should therefore confirm signal levels, control sequencing, output timing, and unused-pin treatment from the official Analog Devices documentation before layout or procurement approval. Existing assemblies should also verify the exact suffix interpretation rather than assuming that a similarly named ADSP-1081 variant is interchangeable.
This page consolidates verified distributor pricing, availability, package information, and sourcing links for ADSP-1081AKD/+. It also distinguishes documented facts from unavailable electrical details and records the absence of a verified, pin-compatible substitute set, helping purchasing and engineering teams avoid unsupported replacement assumptions.

יישומים טיפוסיים
ADSP-1081AKD/+ מתאים עבור 6 יישוםs: Dedicated Digital Signal Processing, Industrial Arithmetic Control Systems, Instrumentation Signal Conditioning, Legacy Equipment Retrofit, Digital Gain and Scaling, Specialized Test and Measurement Equipment.
Dedicated Digital Signal Processing
The ADSP-1081AKD/+ fits a dedicated digital signal-processing subsystem that requires an 8 x 8 binary multiplication function. Its verified DSP-multiplier classification and CMOS implementation allow the product calculation to be performed directly by a dedicated integrated circuit rather than through repeated software addition. The principal engineering trade-off is board area: the hermetically sealed 40-CDIP package is much larger than a surface-mount arithmetic device. Before committing to the part, engineers must obtain the manufacturer timing and electrical specifications to confirm compatibility with the surrounding datapath.
Industrial Arithmetic Control Systems
ADSP-1081AKD/+ can serve as a hardware arithmetic element in an industrial control system that repeatedly combines two 8-bit values. The dedicated 8 x 8 multiplier provides a clear functional block for scaling, compensation, gain, or product calculations. Its ceramic, hermetically sealed 40-pin package may be useful where rugged through-hole construction is preferred. Industrial deployment nevertheless requires verified operating-temperature, supply-voltage, and reliability limits because those details are absent from the supplied distributor excerpts.
Instrumentation Signal Conditioning
The ADSP-1081AKD/+ is applicable to instrumentation architectures in which an 8-bit by 8-bit product forms part of a measurement or calibration path. A dedicated multiplier can simplify control logic by accepting two operands and producing the corresponding digital product. Its through-hole ceramic DIP package supports board-level integration but consumes substantial PCB area compared with modern surface-mount DSP blocks. System engineers must verify output coding, clocking, propagation delay, and signal levels from the official manufacturer documentation before selecting it.
Legacy Equipment Retrofit
ADSP-1081AKD/+ is relevant when maintaining or selectively modernizing legacy hardware that already uses a 40-CDIP digital multiplier. The hermetically sealed, side-brazed ceramic package and 8 x 8 CMOS function match the physical and arithmetic characteristics described by verified distributor records. For a retrofit, engineers should preserve the original footprint, verify every signal against the authoritative pinout, and test both static and dynamic behavior. Available pricing and inventory are as of 2026-10-30 and should be reconfirmed during quotation.
Digital Gain and Scaling
A dedicated ADSP-1081AKD/+ can implement digital gain, scaling, or coefficient multiplication where both operands are 8-bit values. Using the dedicated multiplier avoids consuming processor cycles for repeated shifts and additions, which can simplify deterministic control hardware. The design must still account for result width, overflow behavior, clock timing, and control latency, none of which are available in the supplied records. Those details must be confirmed from the manufacturer datasheet before implementing the multiplier in a new signal-processing chain.
Specialized Test and Measurement Equipment
The ADSP-1081AKD/+ may be used as an arithmetic building block in specialized test and measurement equipment requiring a dedicated 8 x 8 CMOS multiplier. Its DSP-peripheral identity and hermetically sealed 40-CDIP construction make it a candidate for established through-hole instrument architectures. The large ceramic package can simplify manual insertion and serviceability but will limit density compared with surface-mount alternatives. Because noise, power, timing, and temperature specifications are not included in the verified excerpts, laboratory engineers must validate them before high-precision measurement use.

הערות תכנון
Treat the ADSP-1081AKD/+ as a 40-pin through-hole ceramic device rather than a surface-mount part. The verified package is 0.600 inch, or 15.24 mm, wide, so the PCB footprint must provide adequate ceramic-body clearance, adequate hole spacing, and sufficient connector access. Confirm the authoritative pin numbering and signal names before creating the footprint; the verified records identify the package but do not provide a pinout.
Verify the supply-voltage range, input levels, output drive, and power-consumption limits in the official manufacturer documentation before connecting the device. Those electrical values are not included in the supplied distributor data, so a supply rail cannot be selected safely from the available evidence. Decoupling and sequencing must be based on the documented requirements rather than generic assumptions for an older CMOS multiplier.
Do not assume that ADSP-1081AKD, ADSP-1081AKD/+, and ADSP-1081A are interchangeable merely because the listings use similar names. The verified excerpts do not establish the suffix-temperature relationship, pin compatibility, or timing equivalence. For an existing design, match the exact orderable MPN, package, electrical ratings, and pinout; otherwise, rework or a functional equivalent may be required.
Because no clock-frequency or propagation-delay specification is present in the supplied data, treat any high-speed layout as provisional. Keep device outputs away from sensitive analog inputs, provide a stable return path, and use the datasheet-recommended bypass network. If the final design requires operation above a modest clock rate, bench-test ringing and data timing rather than relying on the generic CMOS classification.
