ADSP-1008AJN - 8x8 CMOS Multiplier | Analog Devices
料号： ADSP-1008AJN ✓ 量产中ADSP-1008AJN 概述
A digital multiplier is a semiconductor datapath component that multiplies two binary numbers and presents the result through a parallel output bus. In the broader hierarchy, this device belongs to the DSP peripheral and digital signal-processing IC category rather than an analog amplifier. Its parallel architecture permits multiple operands to be processed during one clock cycle, making it useful when computation throughput is more important than minimizing package count.
The verified source data identifies the ADSP-1008AJN as an 8 x 8 CMOS multiplier with multiplier-accumulator and summer functionality. It provides a 19-bit output data bus, uses 48 terminals, and is packaged in a rectangular PDIP/DIP-48 through-hole package. The commercial temperature grade and CMOS implementation place it in the class of legacy parallel DSP peripherals designed for direct connection to microprocessor or digital-logic buses.
The 48-pin package exposes a relatively large number of parallel data and control connections compared with a compact serial interface. This architecture can simplify a design when the surrounding processor already uses parallel bus timing and does not require a serial multiplier. The trade-off is a high pin count and a larger board footprint compared with modern serial DSP or FPGA-based arithmetic engines.
Typical uses include digital filtering, signal analysis, data-acquisition preprocessing, industrial control, measurement instrumentation, and embedded arithmetic where an 8 x 8 multiplication function is required. Because the available technical data does not state clock rate, input setup time, output propagation delay, supply-current limits, or operating-temperature limits, those values must be confirmed from the manufacturer datasheet before timing-dependent implementation.
When designing around this device, verify the complete 48-pin connection list, control-signal polarity, output-word interpretation, and enable timing from the original ADI documentation. The provided search results identify the device as an 8 x 8 parallel CMOS multiplier, but they do not provide a complete pinout table or detailed timing specifications, so those design-critical details remain marked as needed.
This product record consolidates verified distributor pricing, availability, package information, technology details, lifecycle-related sourcing observations, and practical selection guidance. It also distinguishes a documented same-family candidate from confirmed pin-to-pin alternatives, preventing a parametrically similar part from being presented incorrectly as a guaranteed drop-in replacement.

典型应用
ADSP-1008AJN 适用于 6 应用s: Digital Filtering, Signal Acquisition Preprocessing, Industrial Control Arithmetic, Measurement and Instrumentation, Digital Communication Preprocessing, Embedded Arithmetic Control.
Digital Filtering
The ADSP-1008AJN fits a legacy parallel digital-filter datapath because it performs 8 x 8 multiplication and provides multiplier-accumulator and summer functions for coefficient scaling and state accumulation. Its 19-bit output data bus gives the surrounding bus architecture a defined result width, while the 5 V CMOS supply is compatible with systems designed around same-family logic. The part is most practical where an existing processor interface already includes the required parallel signals. Because the supplied information does not state throughput or propagation delay, verify timing against the filter clock before committing to this implementation.
Signal Acquisition Preprocessing
For data-acquisition preprocessing, the ADSP-1008AJN can provide a dedicated parallel multiplication stage between sampled data and programmable coefficients. Its 8 x 8 multiplier and multiplier-accumulator capability are applicable to scaling, correlation, and weighted-sum operations, while the 19-bit output bus can simplify connection to a wider external datapath. The commercial-grade 48-DIP package favors established through-hole laboratory and industrial control platforms. Verify the input encoding, output truncation, clock phase, and acquisition settling requirements because these details are absent from the supplied excerpts.
Industrial Control Arithmetic
The ADSP-1008AJN is applicable to legacy industrial control systems that require deterministic parallel arithmetic for proportional, compensation, or scaling calculations. The 8 x 8 CMOS multiplier can offload multiplication from a host processor, and the multiplier-accumulator and summer functions support repeated arithmetic operations without reproducing the operation in general-purpose software. The 5 V supply and 48-lead PDIP package align with older control boards. Confirm operating-temperature limits, input and output logic thresholds, and clock timing before using it in newly qualified equipment.
Measurement and Instrumentation
The ADSP-1008AJN can support measurement-instrument datapaths that perform fixed-point scaling or coefficient multiplication after conversion by another circuit. Its parallel 8 x 8 architecture and 19-bit result bus suit systems designed around bus-oriented processors, and the multiplier-accumulator and summing functions can reduce the number of external arithmetic operations. Because the verified listing identifies the device as a DSP peripheral rather than a complete converter or signal conditioner, it must be surrounded by appropriate analog front-end, clocking, and conversion circuitry. Timing and power details require confirmation from the original ADI documentation.
Digital Communication Preprocessing
In legacy digital communication equipment, the ADSP-1008AJN may be used for parallel multiplication during correlation, symbol weighting, or filtering operations. Its CMOS implementation, 5 V supply, and dedicated 8 x 8 arithmetic block are consistent with bus-oriented signal-processing architectures, while the 19-bit output bus provides a defined result path to subsequent logic. The through-hole 48-DIP package is most appropriate for an existing motherboard rather than a compact new radio design. Confirm signal polarity, enable behavior, throughput, and output-code interpretation because the supplied records do not specify them.
Embedded Arithmetic Control
The ADSP-1008AJN can serve as a hardware arithmetic block in an embedded controller that requires multiplication and accumulation independent of its general-purpose processor. Placing the operation in parallel CMOS hardware may reduce processor execution time in an established control design, and the 19-bit output bus allows results to be captured by parallel logic. The DIP-48 footprint is comparatively large, so the approach is most appropriate when board area is already fixed and rework would be costly. Validate sustained throughput, setup and hold timing, and supply-current demand before using the part as a performance upgrade.

关键差异点

- Established 48-DIP integration footprint （对比 ADSP-1081A)
- Parallel result and control architecture （对比 ADSP-21990BBC)
设计说明
Do not treat a similar ADSP-series part as a drop-in substitute without a complete pin-function comparison. The supplied search results identify ADSP-1008AKD, ADSP-1081A, ADSP-2100AKG, and ADSP-21990BBC as possible alternatives, but they explicitly require datasheet and pinout checks. Verify the 48 terminal assignments, control polarity, logic thresholds, output-word structure, and timing against the original ADSP-1008AJN documentation before purchasing a replacement.
Reserve the complete 48-lead PDIP footprint and route all parallel signals before assigning board functions. The verified 19-bit output bus and 8 x 8 multiplier imply numerous data lines, so incorrect routing can prevent operation even when power and logic levels are correct. Confirm the manufacturer pinout and use a verified CAD symbol or footprint rather than inferring terminal positions from a generic DIP-48 library.
The verified device operates from 5 V, but its maximum supply current and per-pin current limits are [DATA_NEEDED: supply-current specifications]. Decouple the 5 V rail according to the manufacturer guidance and account for output-driver loading and any external logic. The estimated rail budget cannot be calculated reliably until the missing current specification, operating frequency, and enabled-output state are confirmed.
The ADSP-1008AJN is a legacy parallel-bus device, so timing margins depend on propagation delay, setup time, hold time, and board loading. The supplied excerpts do not provide those values. Determine the maximum operating frequency from the original datasheet, include trace and connector effects in the budget, and avoid substituting a functionally similar IC whose interface timing is only loosely comparable.
