ADSP-1080AKD/+ - 8x8 CMOS Multiplier | Analog Devices
部品番号: ADSP-1080AKD/+ ✗ 生産終了ADSP-1080AKD/+ 概要
An analog multiplier is a signal-processing semiconductor that multiplies two analog input signals and produces an output proportional to their product. It belongs to the broader analog multiplier and divider hierarchy, which is part of linear and analog signal processing. In digital signal processing and DSP peripheral systems, this multiplication function supports products such as modulation, waveform generation, automatic gain control, correlation, analog signal conditioning, and mixed-signal calculations.
The ADSP-1080AKD/+ provides an 8-bit multiplier architecture using CMOS technology. The available verified product information identifies the device as an 8 x 8 CMOS multiplier, while distributor records classify it as a DSP peripheral multiplier within the analog multiplier/divider category. Its commercial temperature grade and 40-terminal through-hole format are also explicitly identified in the supplied records.
The CDIP-40 package provides a conventional 40-pin dual-inline footprint suitable for through-hole assembly, prototype boards, legacy industrial equipment, and systems designed around the DIP form factor. Because the verified results do not expose the complete electrical tables, power ratings, gain accuracy, bandwidth, input range, output range, or power consumption, those parameters should be confirmed in the Analog Devices ADSP-1080AKD datasheet before a new high-accuracy design is released.
Typical implementation opportunities include laboratory multiplier circuits, DSP accelerator boards, modulation and demodulation blocks, educational analog-computing systems, and replacement of an original 40-pin CMOS multiplier in legacy equipment. The product is most appropriate when an 8 x 8 multiplication function and a DIP-compatible mechanical format are more important than modern surface-mount integration or very low power consumption.
Designers should verify the complete pin assignment, supply voltage, input and output signal limits, settling behavior, and timing characteristics against the manufacturer datasheet before substitution. The available verified records also report RoHS non-compliance, so this component may require a controlled legacy-supply or exemption strategy in newer RoHS-scoped products. Procurement should use traceable authorized channels and confirm the exact suffix and ceramic package construction.
This page combines verified package, architecture, temperature-grade, pricing, and sourcing information with clearly identified engineering gaps, drop-in candidate evaluation, comparison parameters, and practical legacy replacement guidance. It separates confirmed distributor facts from values that still require datasheet verification, supporting faster engineering review without presenting missing electrical characteristics as facts.

主な用途
ADSP-1080AKD/+ の用途: 6 件s: Legacy DSP Accelerator Board, Analog Signal Multiplication, Modulation and Demodulation Circuit, Waveform Generation and Control, Industrial Equipment Repair, Education and Analog Computing.
Legacy DSP Accelerator Board
The ADSP-1080AKD/+ is suitable for a through-hole DSP accelerator board where an 8 x 8 multiplication operation is required without redesigning the original 40-pin footprint. The verified device information identifies it as an Analog Devices CMOS DSP peripheral multiplier in a CDIP-40 package. Its principal benefit is mechanical continuity with legacy boards, although the missing verified power, bandwidth, and accuracy tables require careful review before new routing is released. Engineers should preserve the original supply decoupling and signal-conditioning topology until the manufacturer datasheet confirms the applicable electrical limits.
おすすめ
Analog Signal Multiplication
ADSP-1080AKD/+ can implement analog signal multiplication in laboratory, control, or instrumentation circuits that require the product of two analog signals. Its confirmed 8 x 8 CMOS multiplier architecture provides the required computational function, while the 40-terminal through-hole package simplifies connection to older prototyping systems. Unlike a software multiplier, the analog implementation can operate directly on continuously varying signals. Actual gain accuracy, input range, output range, and bandwidth must come from the ADSP-1080 datasheet because those values were not exposed in the verified search records.
おすすめ
Modulation and Demodulation Circuit
The ADSP-1080AKD/+ fits legacy modulation and demodulation experiments because multiplication is required when one waveform is used to modulate, correlate, or demodulate another signal. Its verified 8 x 8 CMOS architecture supports the fundamental multiplication stage, and the CDIP-40 package allows convenient insertion into educational or industrial prototype boards. The selection must still be validated against the original circuit's carrier frequency, amplitude limits, linearity requirements, and supply rails. Using the original footprint can reduce mechanical changes, but it does not waive the need for an electrical equivalence review.
おすすめ
Waveform Generation and Control
ADSP-1080AKD/+ can serve as the multiplication element in legacy waveform-generation or automatic-gain-control assemblies where two variable signals must be combined. The confirmed 8 x 8 CMOS function and 40-pin through-hole package make it appropriate for equipment designed around the DIP interface rather than a compact mixed-signal module. A functional replacement should preserve the original pinout, supply arrangement, and output impedance assumptions. Before production use, engineers need the manufacturer data for bandwidth, saturation behavior, offset, linearity, and power consumption to ensure the multiplier does not distort time-critical waveforms.
おすすめ
Industrial Equipment Repair
ADSP-1080AKD/+ is directly relevant to repair and obsolescence management for industrial equipment that used an Analog Devices 8 x 8 CMOS multiplier in a 40-pin ceramic DIP package. The through-hole CDIP format permits board-level replacement without converting the design to a surface-mount footprint. Verified commercial-grade and RoHS non-compliance information must be considered when deciding whether the original legacy part remains appropriate for the operating environment. Traceable sourcing and an incoming inspection process are recommended because availability varies between distributors and the verified results do not establish authenticity status.
おすすめ
Education and Analog Computing
The ADSP-1080AKD/+ is useful in educational analog-computing, instrumentation, and DSP demonstration systems because it combines a clearly defined 8 x 8 multiplication function with a conventional 40-pin through-hole package. Students can construct multiplier, modulation, feedback, and analog-computing experiments without relying on simulated multiplier blocks. The large DIP package is less attractive for compact portable equipment, but it makes probing and replacement straightforward. Because the verified records do not provide full dynamic limits, instructional use should include supply, input-range, and output-signal checks based on the official manufacturer documentation.

設計ノート
Do not treat the ADSP-1080AKD, ADSP-1080AKN, and ADSP-1080AJN identifiers as automatically interchangeable. The verified records establish an 8-bit CMOS multiplier family with 40-pin DIP-family packaging, but they do not provide a complete pinout or quantified electrical table. Download the current Analog Devices datasheet, compare supply voltage, input range, output range, accuracy, bandwidth, and temperature limits, and confirm the original package suffix before replacing a component in production equipment.
Preserve the original through-hole footprint and pin routing when repairing a legacy board. Confirm pin 1 orientation, ceramic-package row spacing, and every supply and ground connection from the manufacturer drawing before inserting the CDIP-40 part. Keep sensitive multiplier inputs away from switching nodes and provide the same ground-return arrangement used in the original circuit. A mechanically similar 40-pin package does not by itself establish an electrically equivalent replacement.
Use the manufacturer-specified supply voltage and decoupling arrangement for the ADSP-1080AKD/+; the verified records do not disclose the voltage rating or current consumption. Do not infer a modern regulator's output voltage from the ADSP designation. Review the original board schematic, identify bypass capacitors and their polarity or rating, and reproduce that network before energizing a repaired assembly. The commercial temperature grade and RoHS non-compliance also require attention in equipment qualification.
コンプライアンス情報
Cytech Systems explicitly reports RoHS non-compliance for ADSP-1080AKD. No verified REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification statement was provided. AEC-Q100 is not applicable because this is a legacy commercial-temperature DSP peripheral multiplier rather than an automotive-qualified device.
