ADSP-1010AJN - 16-Bit DSP Multiplier Accumulator | Analog Devices
MPN: ADSP-1010AJN ✗ End of LifeADSP-1010AJN Overview
A digital multiplier/accumulator is a fixed-function arithmetic peripheral used to calculate products and accumulate sequential results inside signal-processing systems. In the broader electronics hierarchy, it belongs to the DSP peripheral category and supports the wider digital signal processing and embedded processing ecosystems. Its dedicated arithmetic function can reduce processor overhead when implementing filters, correlation, scaling, polynomial evaluation, or complex signal-chain operations.
The ADSP-1010AJN provides a 16-bit multiplier with a full 32-bit product and an optional 32-bit accumulator output. The supplied product listings classify it as a linear analog multiplier/divider or DSP peripheral, while the official distributor description identifies it as a high-performance 16-by-16 digital multiplier/accumulator. Its through-hole PDIP-64 package is suited to legacy industrial, instrumentation, communication, and educational systems where a socketed or through-hole implementation simplifies assembly and replacement.
The ADSP-1010AJN is intended for designers building fixed-point arithmetic subsystems around DSP controllers, microprocessors, or general-purpose digital logic. Typical uses include digital filter coefficient multiplication, signal correlation, adaptive arithmetic, waveform generation, and multiply-accumulate stages. Because the device performs a dedicated arithmetic operation, it can offload repeated product calculations that would otherwise consume processor instruction cycles.
The package and signal details must be confirmed against the manufacturer datasheet before layout or replacement. The available verified web data confirms the PDIP-64 package, commercial temperature grade, 16-bit multiplier, 32-bit product output, and optional 32-bit accumulator output. Detailed supply voltage, clock timing, input and output logic levels, control-pin definitions, maximum operating frequency, and absolute maximum ratings were not included in the supplied source extract and therefore are not inferred here.
ADSP-1010AJN procurement should be treated as a lifecycle-sensitive sourcing decision. The verified distributor results include marketplace availability from Rochester Electronics and multiple authorized or independent distributor listings, but they do not provide a complete current manufacturer lifecycle statement. Engineers should confirm stock, lead time, exact package markings, and date-code traceability before production release.
This page combines the verified distributor specifications, sourcing references, package information, and practical selection guidance for the ADSP-1010AJN. It also distinguishes confirmed data from unresolved details and avoids presenting guessed pinout, timing, pricing, or lifecycle information as manufacturer facts.

ADSP-1010AJN rectangular Pin Configuration Guide
Pin configuration for ADSP-1010AJN (rectangular package). Pin numbering, functions, and connection diagrams are defined in the manufacturer datasheet. Refer to it for the exact footprint and soldering guidelines.

Refer to the datasheet for full pin configuration.
Typical Applications
ADSP-1010AJN is suitable for 6 applications: Digital Filter Multiply-Accumulate Stage, Signal Correlation and Detection, Industrial Instrumentation Signal Processing, Communication Signal Conditioning, Adaptive Control and Polynomial Evaluation, Waveform Generation and Table Processing.
Digital Filter Multiply-Accumulate Stage
The ADSP-1010AJN fits a fixed-point digital filter arithmetic block because its verified function is a 16 x 16-bit multiplier/accumulator with a full 32-bit product and optional 32-bit accumulator output. It can execute coefficient multiplication followed by sequential accumulation while a DSP or microprocessor controls data movement and timing. Using a dedicated peripheral may reduce host arithmetic overhead, although the actual throughput depends on the clock and timing limits documented in the manufacturer datasheet.
Recommended
Signal Correlation and Detection
The ADSP-1010AJN is appropriate for correlation, matched-filter, and sequence-detection arithmetic that repeatedly multiplies signal samples by coefficients and accumulates the results. The 16 x 16-bit multiplier supports two 16-bit operands, while the full 32-bit product avoids retaining only an immediately truncated result. The optional 32-bit accumulation supports longer arithmetic sequences, subject to confirmation of exact output-selection and timing behavior in the datasheet.
Recommended
Industrial Instrumentation Signal Processing
The ADSP-1010AJN can serve as a dedicated arithmetic peripheral in legacy industrial instrumentation that uses 16-bit fixed-point samples and coefficients. Its through-hole PDIP-64 package is convenient for boards that use socketed logic or manual assembly rather than high-density surface-mount construction. The commercial-grade designation suits ordinary commercial equipment, but designers must confirm supply voltage, logic thresholds, timing, and thermal limits before incorporating the device.
Recommended
Communication Signal Conditioning
The ADSP-1010AJN can be used in communication-system subcircuits that require repeated fixed-point multiplication and summation, including filtering, modulation support, and sample-domain arithmetic. The dedicated 32-bit product and optional 32-bit accumulator outputs provide useful numerical width for intermediate results. Its legacy PDIP package makes it most relevant to existing or manually serviced equipment; new high-volume designs should compare its operating rate and availability against current DSP peripherals.
Recommended
Adaptive Control and Polynomial Evaluation
The ADSP-1010AJN can accelerate coefficient-dependent operations in adaptive control and polynomial evaluation, where a sequence of products must be summed. A host processor can update coefficients and coordinate each arithmetic cycle while the dedicated multiplier/accumulator performs the arithmetic operation. Before selecting it, verify clock throughput, pipeline behavior, and accumulator-control semantics; those details were not included in the supplied source extract and must be taken from the manufacturer datasheet.
Recommended
Waveform Generation and Table Processing
The ADSP-1010AJN is applicable to waveform-generation systems that repeatedly multiply a time or phase value by a coefficient and accumulate the result. Such operations occur in polynomial approximations, sinusoidal synthesis, and digitally generated waveform tables. The dedicated arithmetic path can separate the multiply-accumulate operation from host memory and control tasks. The implementation should preserve the full 32-bit product where needed and must follow the confirmed output-width and overflow behavior in the datasheet.

Key Differentiators
- Dedicated 32-bit intermediate product (vs ADSP-1010)

- Commercial-grade 64-pin through-hole implementation (vs ADSP-1011)
Design Notes
Do not approve a replacement or new PCB layout from the family name alone. The verified data establishes a 64-terminal PDIP package but does not provide pin names or timing. Compare the exact ADSP-1010AJN package drawing, power pins, clock inputs, control inputs, product outputs, accumulator outputs, and no-connect pins against the selected replacement. A device can have the same DIP outline while differing in clock polarity, control logic, output enable behavior, or signal timing.
Route the 64-pin through-hole device with unobstructed access to all leads, and provide clean grounding and decoupling according to the manufacturer application guidance once those values are available. Keep high-speed clock and data traces short, avoid routing them adjacent to unrelated switching nodes, and use a solid ground-plane arrangement for the digital logic. Because the pinout and supply connections are absent from the supplied data, do not assign capacitors or test points to specific pins without the official datasheet.
Estimate worst-case dissipation using the actual supply voltage, output-swing rate, clock frequency, and load rather than a generic through-hole thermal assumption. Estimated: power dissipation equals supply voltage multiplied by average device current, but the current values are not present in the verified extract. Add them only after obtaining the electrical characteristics. Verify startup current, supply tolerance, and decoupling capacitance from the datasheet, especially if the device is clocked continuously or its outputs drive substantial capacitive loads.
Compliance Information
The supplied verified data identifies the device as commercial grade but does not provide RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification statements.
