WM8144CCPT 개요
An audio-channel IC is a specialized integrated circuit that handles one or more functions within an audio signal chain, such as conditioning, conversion, channel selection, or control. These devices sit between audio sources and downstream amplifiers, converters, microphones, speakers, or digital audio processors. Their performance requirements commonly include low signal distortion, stable channel behavior, compatible logic levels, and electrical characteristics matched to the intended audio architecture. Because the verified WM8144CCPT records provide only the part identity and broad category, device-specific claims should not be inferred without the original Wolfson Microelectronics or Texas Instruments documentation.
The visible sourcing records support three practical points about WM8144CCPT. DigiKey Marketplace labels it as an audio channel from Texas Instruments, Octopart lists it as an integrated circuit for audio special purposes, and Rochester Electronics distribution data reports active production status. The supplied pricing excerpt gives a starting unit price of $4.07 at one-unit quantity and mentions volume discounts at 10, 100, 500, and 1,000 units. Availability language differs among marketplaces, so a purchase decision should use a current authorized-distributor quote and manufacturer inventory confirmation.
WM8144CCPT is most relevant to legacy or industrial audio platforms in which the original circuit was designed around this exact device. In such systems, preserving the original device is generally safer than selecting a generic audio IC with similar nominal functionality. Any substitute must be checked for exact package dimensions, lead pitch, exposed-pad requirements, pin assignments, supply voltage, clocking, control interface, analog performance, and lifecycle status. The verified information identifies Rochester Electronics as the source of the distributed WM8144CCPT offer, so procurement documentation should also confirm the original manufacturer and authorized sourcing chain.
The key engineering constraint is that the available verified data is incomplete. Mounting type, operating-temperature range, package case, absolute maximum ratings, supply voltage, channel count, resolution, interface type, and pin assignments are not stated in the supplied records. These values must be read from the applicable manufacturer datasheet before schematic capture, footprint selection, or production release. This prevents the mistake of treating a distributor category label as a substitute for full electrical and mechanical documentation.
A sound sourcing workflow is to compare the distributor listing, Rochester Electronics product record, and Octopart cross-reference data against the original system documentation. Confirm that the ordered suffix CCPT matches the required package and ordering configuration, then request current stock and traceable shipment details. For repair and redesign programs, also inspect the board assembly records for markings or bill-of-material entries that may reveal the original manufacturer designation.
This page consolidates the verified sourcing status, pricing basis, category placement, and data gaps for WM8144CCPT while avoiding unsupported electrical claims. It is intended to support initial part identification and procurement research, not to replace the manufacturer datasheet, reference schematic, or board-level compatibility checklist.

Legacy Audio System Repair
WM8144CCPT is appropriate for repairing a qualified audio assembly that identifies this exact Texas Instruments orderable part. The verified distributor data describes it as an Audio Special Purpose device and reports active production through Rochester Electronics, which makes it the lowest-risk maintenance option when the original BOM, package, and pin configuration are unchanged. The repair path should preserve the existing schematic, layout, decoupling, and signal routing rather than improvise a substitute. Because the supplied records do not provide a pinout or package dimensions, technicians should verify those details against the applicable manufacturer datasheet before replacing the component. Current stock and traceability should be confirmed at order time because marketplace inventory can change quickly.
추천
Audio Channel Interface
The Audio Special Purpose classification makes WM8144CCPT relevant to systems that need a dedicated channel-level audio function rather than a general-purpose codec. A repair or update program should use the device only when the original architecture confirms its input, output, control, and supply behavior. Its verified distributor identity supports targeted procurement, but no verified source states channel count, converter resolution, clock frequency, or digital format. Engineers must therefore treat the part as an exact-match maintenance component and retrieve the manufacturer documentation before describing its signal path or changing interface parameters.
추천
Industrial Control Console Audio
An industrial control console can retain WM8144CCPT during a targeted audio-path repair when the original board was built around this exact device. Active production status is favorable for long-tail maintenance, and the reported $4.07 starting unit price as of 2026-10-23 supports budgeting a small replacement inventory. Nevertheless, the verified data leaves operating temperature, package, mounting type, and electrical ratings unspecified. Those omissions are critical for industrial use, so engineers should confirm the exact production specification, long-term availability, and environmental compliance before treating the part as suitable for new industrial deployments.
추천
Broadcast Monitoring Equipment
WM8144CCPT may be considered for maintenance of broadcast-monitoring equipment that originally specifies the exact WM8144CCPT audio channel IC. Preserving the original part avoids introducing undocumented differences in signal routing, control timing, or board geometry. The supplied Octopart and DigiKey records support sourcing and lifecycle cross-checking, while the Rochester Electronics record reports active inventory. A broadcast application nevertheless requires confirmation of operating-temperature limits, supply tolerance, channel performance, and regulatory constraints from the controlling datasheet; none of those technical values are available in the verified search excerpts.
추천
Communication Equipment Audio Path
WM8144CCPT can serve as a maintenance component in communication equipment whose original engineering documentation specifies that orderable part. The specialized Audio ICs classification and the active lifecycle indication make exact replacement more defensible than selecting a generic codec with an unverified interface. Because the verified data does not disclose digital timing, analog noise, clocking, or supply details, engineers must avoid changing clock, filtering, or channel configuration during repair. A modern interface IC may offer a better path for a new platform, but it becomes an option only through a deliberate board redesign and signal-performance validation.
추천
Imaging System Data Acquisition
The base WM8144 designation is associated with an integrated 10-bit data-acquisition system for imaging applications, according to the verified datasheet-search result. That association makes the WM8144 family relevant to CCD imaging signal-conditioning and digitization contexts, but it does not prove that the WM8144CCPT ordering code shares every base-device feature. Any use in an imaging board should begin by reconciling the complete ordering suffix with the manufacturer datasheet revision. The verified records do not provide channel count, sampling rate, input range, or package details, so a new imaging design cannot responsibly be qualified from the supplied material alone.

설계 노트
Do not substitute WM8144CCPT solely because another device is also described as an audio IC. The verified WM8144CCPT records do not disclose the package, pinout, supply voltage, interface, or performance ratings, so the first design rule is to recover the controlling manufacturer document and original BOM. Confirm that the CCPT ordering suffix corresponds to the installed footprint and qualification requirements. A same-category IC with a different package or digital interface requires PCB changes and is not a drop-in replacement.
Before power-up, obtain the exact absolute-maximum ratings, recommended supply range, sequencing requirements, and power-consumption figures for WM8144CCPT. The verified distributor excerpts do not provide these values. During repair, inspect the original board for evidence of damaged decoupling, contaminated analog ground, or an overloaded upstream rail, and reproduce the manufacturer's layout and component-selection requirements. Applying a generic 5 V or 3.3 V assumption to an unspecified audio IC can permanently damage the device or obscure the original failure mechanism.
Preserve the original PCB footprint, pad pattern, pin-one orientation, and exposed-pad or thermal-pad treatment when replacing WM8144CCPT. The supplied records show a dash for package and case, and no authoritative pinout is present, so footprint conclusions cannot be made from the suffix. Before assembly, compare the ordered part's mechanical drawing with the board's land pattern and check whether the original assembly used a specific solder profile. Rework a prototype with continuity and thermal verification before repeating the operation on production hardware.
Treat WM8144CCPT as an exact-match service component unless the manufacturer documentation proves otherwise. Verify analog input and output routing, reference voltage, clock source, control levels, grounding, and filtering against the original schematic. The verified records do not state sample rate, resolution, channel configuration, or digital interface, and the base WM8144 search result concerns a 10-bit imaging acquisition system. Consequently, adjusting clocks, gain, or channel mapping from the distributor category alone could produce invalid data or audible faults.
규정 준수 정보
The supplied verified records do not state environmental, automotive, lead-free, halogen-free, or conflict-minerals compliance. Compliance must be confirmed for the exact ordering code and production lot.
