ADSP-1008AKN - 8-Bit CMOS Multiplier | Analog Devices
MPN: ADSP-1008AKN ✓ সক্রিয়ADSP-1008AKN সারাংশ
A digital multiplier is a combinational or sequential arithmetic circuit that multiplies two binary values and produces a wider mathematical result. The ADSP-1008AKN belongs to the digital signal-processing IC hierarchy, where multiplier-accumulator structures accelerate repeated multiply-and-add operations. Compared with implementing multiplication entirely in software or with discrete gates, a dedicated multiplier can reduce processor execution time and simplify real-time arithmetic pipelines.
The verified product information identifies the ADSP-1008AKN as an 8-bit DSP multiplier-accumulator/summer with a multi-channel arithmetic structure. It is manufactured using CMOS technology and is offered in a PDIP-48 package. Its documented temperature range extends from -65 °C to +150 °C, making it suitable for industrial and extended-temperature equipment when the complete system requirements, supply rails, and timing limits are satisfied.
In a typical arithmetic pipeline, one operand is applied to a multiplier input, the second operand is applied to the other input, and the resulting product is routed into an accumulator. The summer function can combine this result with a previously stored value. This arrangement is applicable to FIR filtering, modulation, waveform generation, correlation, scaling, and control calculations when the implementation requires a dedicated arithmetic block rather than a general-purpose microcontroller instruction.
Typical uses include digital filter coefficient multiplication, amplitude and gain control, modulation and demodulation arithmetic, instrumentation signal processing, and embedded control systems. The 48-pin PDIP package also favors through-hole prototyping, legacy industrial equipment, and repair applications where leaded components are easier to inspect or replace than very fine-pitch surface-mount packages.
The principal design consideration is that the complete timing, supply-voltage, clock, and logic-level requirements must be taken from the manufacturer datasheet before implementation. Designers should also account for the propagation delay of the multiplier and accumulator path when clocking arithmetic stages. The manufacturer datasheet is the controlling source for input coding, output behavior, control signals, and timing constraints.
This page consolidates verified distributor information, package details, temperature information, pricing evidence, replacement-search results, and practical selection guidance. It distinguishes confirmed target-part data from unverified replacement candidates so engineers can identify what is known without treating search-tool suggestions as guaranteed drop-in equivalents.

সাধারণ ব্যবহার
ADSP-1008AKN এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Digital FIR Filter Multiplier-Accumulator, Instrumentation Signal Conditioning, Amplitude and Gain Control, Waveform Generation, Modulation and Demodulation Arithmetic, Legacy Control and Repair Systems.
Digital FIR Filter Multiplier-Accumulator
The ADSP-1008AKN fits digital FIR-filter arithmetic where an 8-bit by 8-bit multiplication result must be accumulated with a previous sample. Its multiplier-accumulator/summer function provides the arithmetic block needed for sample-by-sample coefficient multiplication and summation. The verified 48-pin PDIP package is also practical for prototypes and legacy through-hole assemblies. Before implementation, confirm clock timing, operand coding, accumulator behavior, and output latency from the manufacturer datasheet.
Instrumentation Signal Conditioning
The ADSP-1008AKN can support arithmetic signal-conditioning paths that multiply a measured value by a programmable scale factor and accumulate or sum related products. The confirmed 8-bit by 8-bit multiplication capability and multi-channel arithmetic structure suit compact digital measurement and control equipment. Its -65 °C to +150 °C range covers extended-temperature industrial environments. Supply voltage, control interface, and throughput must be verified before the device is selected for precision instrumentation.
Amplitude and Gain Control
A programmable gain or amplitude-control block can use the ADSP-1008AKN to multiply an 8-bit signal value by an 8-bit coefficient. This permits the gain factor to be stored as digital data and changed without changing analog feedback networks. The integrated summer can support accumulation stages in larger arithmetic pipelines. The main design issue is timing: propagation delay and maximum operating frequency were not included in the verified records and must be established from the manufacturer datasheet.
Waveform Generation
The ADSP-1008AKN is applicable to digital waveform-generation architectures that require repeated multiplication and accumulation of stored constants and state values. Its 8-bit by 8-bit CMOS multiplier can form products used in polynomial evaluation, interpolation, or coordinate transformations. The PDIP-48 package makes the device convenient for laboratory and legacy controller assemblies. Engineers must confirm signed or unsigned operand coding, output width, and timing against the datasheet before implementing a waveform table.
Modulation and Demodulation Arithmetic
The ADSP-1008AKN can serve as a dedicated arithmetic element in modulation, demodulation, and correlation systems where repeated multiply-and-add operations determine signal products. The verified multiplier-accumulator/summer function and multi-channel arithmetic structure align with parallel signal-processing pipelines. Its extended -65 °C to +150 °C temperature specification makes it potentially useful in industrial communication equipment. Carrier timing, signal coding, and throughput remain items for datasheet verification.
Legacy Control and Repair Systems
The ADSP-1008AKN is particularly relevant to legacy industrial controllers, test equipment, and repair platforms that use leaded 48-pin DIP components. The through-hole PDIP-48 format simplifies socketed assembly, inspection, and replacement where modern surface-mount packages would be impractical. Its 8-bit CMOS multiplier can accelerate arithmetic previously handled by a processor or discrete logic. Designers should confirm supply rails, clock compatibility, and pin assignments because those details were not supplied in the verified records.

ডিজাইন নোট
Do not substitute the ADSP-1008AKD without checking its exact terminal map, package construction, temperature grade, and timing. The supplied cross-reference evidence identifies it only as a potential alternative and explicitly warns that pinout checks are required. A 48-pin package match alone does not prove drop-in compatibility because renamed power, clock, control, and arithmetic signals can prevent operation or damage surrounding circuitry.
Treat the ADSP-1008AKN as a clock-sensitive digital device and place it close to the source of its timing and digital signals. The verified data does not provide rise-time, fall-time, or setup-and-hold limits, so the manufacturer datasheet must define trace topology, grounding, and timing constraints. Keep return paths continuous and avoid routing operand or accumulator signals across unrelated switching stages without a deliberate impedance and isolation plan.
Determine the required supply voltage, decoupling configuration, and power-consumption limits from the manufacturer datasheet before laying out the 48-pin device. The supplied records confirm CMOS technology but do not provide operating voltages or current ratings. Place the required bypass capacitors at the device power pins according to the datasheet layout, preserve adequate return paths, and verify supply sequencing if multiple rails are present in the target system.
The verified operating-temperature range of -65 °C to +150 °C should not be treated as a guarantee that every system is qualified for the full range. Account for socket contact resistance, PCB temperature gradients, enclosure heating, and thermal cycling in legacy through-hole designs. Confirm which pins carry supply and ground, and verify that the chosen DIP socket and assembly process can tolerate the operating environment and required insertion cycles.
