ADSPLKST-115 Digital Signal Processor | Analog Devices
料号： ADSPLKST-115 ✗ 停产ADSPLKST-115 概述
A digital signal processor is a specialized microprocessor architecture optimized for filtering, transforms, control algorithms, and other operations involving repeated arithmetic on sampled signals. In the broader semiconductor hierarchy, a DSP is a microprocessor, a programmable controller, and an integrated circuit. DSP devices commonly combine hardware multipliers, accumulators, and parallel execution resources with memory and peripheral interfaces so that time-domain or frequency-domain signal-processing workloads can be completed with predictable instruction throughput.
The verified distributor evidence confirms that ADSPLKST-115 belongs to the Analog Devices digital signal processor portfolio and appears under the broader Digital Signal Processors (DSP/DSC) catalog category. It also identifies Analog Devices as the original manufacturer in the DigiKey Marketplace record. Beyond those catalog facts and the listed price, no verified technical ratings were supplied. Consequently, details such as core count, arithmetic word length, instruction set, operating frequency, memory interface, and I/O voltage cannot be asserted from the provided evidence.
The MPN structure ADSPLKST-115 is associated in distributor indexes with a DSP rather than a conventional general-purpose microcontroller, amplifier, or interface circuit. That classification is important for system planning because DSP procurement decisions normally depend on algorithm throughput, supported data formats, deterministic execution behavior, and the availability of development tools. Those characteristics are not quantified in the supplied verified data and should be confirmed against the original Analog Devices or Rochester Electronics documentation before schematic capture.
Likely engineering contexts include digital filtering, signal conditioning, communications waveform processing, modulation, spectral analysis, and embedded control of sampled signals. These applications are category-level use cases rather than manufacturer-stated applications for this exact MPN. Any specific deployment should first confirm the clock rate, arithmetic precision, memory map, peripheral set, voltage domains, and package from an authoritative datasheet. The verified distributor records explicitly expose datasheet, package, and pinout resources, but no manufacturer PDF link was included in the supplied data.
A key procurement precaution is to verify authenticity and lifecycle status before committing to a design. ADSPLKST-115 is indexed by Rochester Electronics at DigiKey and by Analog Devices at LCSC, so legacy or surplus inventory sourcing is involved. Buyers should request traceability, date-code information, operating-temperature grade, and documentation with the purchased lot. The $5.9249 figure is a starting distributor price as of 2026-10-28 rather than a guaranteed volume price.
This page combines verified catalog classification, current distributor pricing, source traceability, and drop-in replacement screening with the supplied web records. It deliberately does not invent processor specifications, pin assignments, lifecycle claims, or substitute part numbers that those records do not establish. Engineers should use the linked manufacturer or authorized-channel documentation to validate all board-level assumptions.

典型应用
ADSPLKST-115 适用于 6 应用s: Digital Filtering Systems, Communications Waveform Processing, Industrial Signal Conditioning, Audio and Measurement Processing, Spectral Analysis and Transform Workloads, Legacy Embedded Control Systems.
Digital Filtering Systems
The ADSPLKST-115 can be evaluated for digital filtering functions because the verified distributor records classify it as a digital signal processor, or DSP/DSC. A DSP-oriented processor is generally suited to repeated multiply-accumulate operations used in finite impulse response and infinite impulse response filters, provided its arithmetic precision, throughput, memory bandwidth, and deterministic execution behavior satisfy the algorithm. LCSC identifies the device in stock at a starting price of $5.9249 as of 2026-10-28, making it potentially relevant to legacy filter-board maintenance. However, the supplied data does not disclose clock rate, word length, memory, or software support. Those requirements must be confirmed before selecting this exact processor.
推荐
Communications Waveform Processing
ADSPLKST-115 is a relevant candidate for legacy communications waveform-processing boards because DSP processors are used to implement modulation, demodulation, interpolation, filtering, and spectrum-related routines. The verified LCSC listing identifies the part as an Analog Devices DSP/DSC and reports in-stock availability, while DigiKey indexes the same MPN through Rochester Electronics for legacy sourcing. No verified specifications establish carrier-rate support, fixed-point performance, memory bandwidth, or peripheral interfaces, so engineers must not infer suitability from the generic DSP classification alone. Existing-board continuity, processor toolchain availability, and exact package equivalence should determine whether this part is an appropriate replacement candidate.
推荐
Industrial Signal Conditioning
ADSPLKST-115 may apply to industrial signal-conditioning equipment that performs sampled-signal filtering, scaling, limit detection, or control calculations. The verified records support an Analog Devices DSP/DSC classification and show distributor availability through LCSC and the DigiKey Marketplace, but they provide no analog-interface specifications. Confirm the available I/O voltage, converter interface, serial ports, timer resources, and package before connecting sensors or transducers to the processor. Because the supplied source price is only a starting figure of $5.9249 as of 2026-10-28, production planners should also confirm obsolescence risk, traceability, and whether a newer supported processor would reduce lifecycle exposure.
推荐
Audio and Measurement Processing
The ADSPLKST-115 is a candidate for legacy audio or measurement processing because DSP processors are commonly used for real-time sample transformation and filtering. Its distributor listings identify the MPN as a DSP/DSC from Analog Devices, and LCSC provides package, pinout, and BOM resources alongside the $5.9249 starting price as of 2026-10-28. The supplied snippets do not publish sampling-rate limits, signal-to-noise performance, fixed-point or floating-point formats, or the processor clock. Those parameters must be verified before assessing a replacement in an existing audio or test-instrument design.
推荐
Spectral Analysis and Transform Workloads
ADSPLKST-115 may be relevant to spectral-analysis or transform-based legacy instrumentation because the part is indexed as a dedicated digital signal processor. Real-time FFT, filtering, and spectral algorithms depend on deterministic interrupt behavior, memory bandwidth, and arithmetic throughput, none of which are quantified in the provided verified data. Procurement is straightforward through the listed LCSC and Rochester Electronics channels, with LCSC reporting the component in stock, but engineers must obtain the original documentation to establish processor capability. A drop-in substitution should not be assumed merely because another part is also a DSP.
推荐
Legacy Embedded Control Systems
ADSPLKST-115 can be considered for maintenance of legacy embedded systems that were originally built around an Analog Devices digital signal processor. Its LCSC record identifies product number C3587886 and reports an in-stock starting price of $5.9249 as of 2026-10-28, while the DigiKey Marketplace listing points to Rochester Electronics LLC and part number 2156-ADSPLKST-115-ND. These sourcing indicators are useful for repair planning. The supplied records do not establish exact package, pinout, processor peripherals, operating temperature, or lifecycle commitment, all of which remain essential qualification items for long-lived industrial or service equipment.

- Documented sourcing channel （对比 TMS320C10FNLR)
设计说明
Do not treat the DSP/DSC label as sufficient evidence for a drop-in replacement. The verified ADSPLKST-115 records do not publish the package, pinout, clock, memory interface, or I/O voltage, while the cross-reference search returned no documented substitute. Before changing a component designation, obtain the exact package drawing and pin list, then compare every power pin, ground connection, clock input, memory interface, peripheral signal, operating-temperature grade, and software bootstrap requirement. The $5.9249 starting price is useful for initial sourcing only and is not a qualification of component equivalence.
Confirm the mechanical footprint from the documentation associated with the purchased inventory rather than inferring it from the MPN. Legacy Analog Devices DSP listings may involve package or revision differences that do not appear in distributor snippets. Compare land pattern, lead pitch, body dimensions, thermal pad or exposed-area requirements, component height, and pin-one orientation. If the source package cannot be confirmed, treat any replacement as a possible redesign rather than a board-level substitution and reserve PCB space for mechanical alternatives.
Validate all supply-rail tolerances, I/O levels, and power-sequencing requirements against the original processor documentation before energizing a replacement board. The supplied data does not identify the ADSPLKST-115 operating voltage, current consumption, or voltage domains. Check digital and analog rails separately, confirm I/O tolerance against external signals, and review decoupling values recommended by the manufacturer. Because no verified SOA data applies to this digital processor, thermal planning should be based on the confirmed package dissipation data rather than generic switching-device assumptions.
合规信息
The supplied distributor records do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Obtain lot-specific compliance documentation from the seller or manufacturer before use in regulated production.
