WM8144-12CPT CPT Audio Channel IC | Texas Instruments
N.º de pieza: WM8144-12CPT ✓ ActivoWM8144-12CPT Descripción general
An audio-channel IC is a semiconductor that processes, converts, buffers, or conditions audio signals within an audio signal chain. Such devices may form part of a signal path connecting microphones, line-level sources, analog-to-digital converters, digital-to-analog converters, amplifiers, and downstream digital audio processors. In the broader component hierarchy, the WM8144-12CPT belongs to the integrated-circuit category, the audio-special-purpose subcategory, and ultimately the broader semiconductor and signal-processing device families.
The strongest verified procurement attributes are the exact manufacturer part number, Texas Instruments branding, audio-channel classification, CPT package suffix, distributor availability, and a quoted $4.5282 unit price as of 2026-10-29. The LCSC result explicitly reported the WM8144-12CPT as in stock, while DigiKey described the listing as available to buy and ship. These commercial signals are useful for preliminary sourcing but do not establish production status, quantity discounts, or long-term supply guarantees.
The available search records do not expose verified specifications for supply voltage, analog input range, output type, sample-rate support, resolution, signal-to-noise ratio, clock interface, control interface, or channel architecture. Consequently, an engineer must not infer those values from the “-12” suffix or from generic descriptions of Wolfson audio devices. The correct procedure is to download the WM8144 family documentation, confirm the orderable suffix, and cross-check every electrical limit against the intended application.
Typical design roles for this device family include audio acquisition, analog audio conditioning, and interfaces between analog audio sources and digital audio systems. Candidate deployments include industrial monitoring equipment, communications terminals, test and measurement instruments, and compact embedded audio products. The WM8144-12CPT should be selected only after verifying that its documented input range, conversion behavior, clocking, and interface requirements match the selected codecs, processors, and analog front end.
The main procurement risk is that distributor snippets provide commercial information but omit the technical document needed for schematic capture. Before ordering, request the current manufacturer datasheet, confirm the exposed-pad or thermal requirements of the CPT package, and check pin compatibility for any replacement. Likewise, verify absolute maximum ratings, decoupling requirements, layout recommendations, and application-circuit values rather than copying a generic reference design.
This page distinguishes verified catalog and purchasing facts from unavailable technical data, provides a direct manufacturer documentation link for review, and identifies candidate same-brand family alternatives without inventing unsupported electrical specifications. It is intended to accelerate sourcing and initial engineering review while preserving the need for datasheet-level validation before PCB release or production commitment.

Aplicaciones típicas
WM8144-12CPT es adecuado para 6 aplicacións: Industrial Audio Monitoring, Communications Terminal Audio, Test and Measurement Audio Front End, Portable Embedded Audio Product, Microphone Signal Conditioning, Audio Interface and Learning Platform.
Industrial Audio Monitoring
The WM8144-12CPT is a candidate for audio-monitoring equipment because distributor records classify it as an audio-channel integrated circuit rather than a general-purpose logic device. In an industrial monitoring design, it could be evaluated within an analog audio acquisition chain that converts or conditions signals before they reach a digital processor. The verified $4.5282 unit price as of 2026-10-29 provides an initial budgeting point. Before selecting it, engineers must confirm the documented signal range, channel count, clocking method, supply voltage, and operating-temperature limits; none of those technical values appeared in the supplied records. The same-brand WM8144CPT and WM8144CCPT should be considered for configuration reviews, but neither is a confirmed drop-in replacement.
Recomendado
Communications Terminal Audio
A communications terminal can require a dedicated path for microphone or line-level audio, making the WM8144-12CPT worth evaluating where an audio-channel IC fits the available board space. Its manufacturer identity, CPT package suffix, and current $4.5282 quoted price as of 2026-10-29 make it suitable for preliminary component selection. Actual suitability depends on documentation that was not supplied, including input range, conversion architecture, supported sample rate, digital interface, and noise performance. The WM8144CPT may be considered if the -12 option is not functionally required, while WM8144CCPT may be reviewed if its ordering configuration matches the intended temperature or qualification requirements.
Recomendado
Test and Measurement Audio Front End
The WM8144-12CPT may be evaluated as the audio-channel element of an instrument front end that accepts an analog source and transfers it into a measurement or processing chain. Its verified audio-channel classification is relevant to this use, and the quoted $4.5282 price as of 2026-10-29 permits early budget allocation. Designers still need the manufacturer datasheet to establish whether the device supports the required signal bandwidth, resolution, dynamic range, clocking, and calibration architecture. The WM8144CPT and WM8144CCPT should be included in an internal comparison because they share the WM8144 family and CPT suffix, but firmware and schematic changes may be necessary if their suffix options differ.
Recomendado
Portable Embedded Audio Product
The WM8144-12CPT can be evaluated for portable embedded audio products where the board requires an integrated audio-channel function and low-power operation. The supplied distributor data confirms the exact MPN, Texas Instruments origin, CPT package suffix, and a $4.5282 unit price as of 2026-10-29. It does not reveal current consumption, standby behavior, supply voltage, or exposed-pad requirements, which are decisive in portable systems. Those parameters must be taken from the manufacturer datasheet and compared with the device’s documented package thermal characteristics. The WM8144CPT and WM8144CCPT are appropriate same-brand review candidates, but substitution should wait until option-code behavior and pin functions are confirmed.
Recomendado
Microphone Signal Conditioning
The WM8144-12CPT is a candidate for microphone or other low-level audio signal-conditioning stages because it is listed specifically as an audio-channel IC. A usable design would also require microphone biasing, protection, gain control, and routing components chosen from the manufacturer’s documented application circuit. The verified $4.5282 quoted price as of 2026-10-29 supports preliminary cost comparison, but no verified gain, input impedance, noise, or supply data was supplied, so the part should not be selected from generic expectations. The WM8144CPT and WM8144CCPT may be preferable if their suffix options provide the required configuration, subject to direct comparison of the WM8144 family documentation.
Recomendado
Audio Interface and Learning Platform
The WM8144-12CPT can be evaluated for an educational or prototyping platform that demonstrates an analog-to-digital audio path. Its documented availability through multiple distributors and quoted $4.5282 price as of 2026-10-29 make procurement straightforward for a small build. The platform should nevertheless be designed around the exact manufacturer pinout, supply recommendations, and application circuit rather than a generic audio-interface schematic. The same-brand WM8144CPT and WM8144CCPT can be ordered for parallel evaluation of the family’s suffix configurations. Because no verified pinout or electrical table was included in the supplied records, this page avoids assigning individual pins or claiming drop-in interchangeability without manufacturer confirmation.

Notas de diseño
Do not treat the WM8144 family name or CPT suffix as a substitute for a complete ordering-table comparison. The target includes a -12 option designation, while the identified alternatives use different suffixes. Before schematic capture or procurement substitution, compare the manufacturer ordering table, pin functions, electrical characteristics, and package drawings. This is particularly important for an audio-channel IC because configuration differences can alter gain, filtering, routing, or qualification without changing the external package code.
The supplied sources do not provide the WM8144-12CPT supply-voltage range, quiescent current, or digital-interface voltage levels. Do not assume compatibility with a 3.3 V or 5 V system solely from the audio-category classification. After obtaining the manufacturer datasheet, verify every rail, sequencing requirement, decoupling value, and exposed-pad connection against the selected audio processor. The recommended application circuit should be treated as the authority for power-network implementation.
Confirm the exact CPT package dimensions, lead pitch, exposed pad, and maximum power-dissipation limits before committing PCB land patterns. The web records expose the CPT suffix but not a verified package drawing or pin table, so an inferred footprint is not sufficient. Route analog and digital returns carefully, keep switching-supply and high-current return paths away from the audio input region, and use the manufacturer’s recommended decoupling and grounding arrangement once those values are available.
The only verified unit-price value is $4.5282 as of 2026-10-29, and no quantity-break schedule was supplied. Do not interpret the repeated tiers in this dataset as confirmed volume pricing. Obtain a quotation for the intended production quantity and validate minimum order quantity, lead time, date code, packaging method, and authorized-channel status. Distributor stock reported by LCSC and DigiKey should also be reconfirmed before placing a build-dependent order.
