Cirrus Logic WM8762CGED is a 24-bit stereo digital-to-analog converter IC operating up to 192 kHz and housed in an 8-pin SOIC package. Verified distributor data identifies it as a serial audio DAC with a 24-bit resolution, 192 kHz capability, and an 8-SOIC format. A DAC is a data-conversion semiconductor that transforms digital audio samples into left- and right-channel analog voltages. In the signal hierarchy, the WM8762CGED belongs to the digital-to-analog converter class, then to the ADC/DAC family and the broader signal-conversion and audio interface categories. Its stereo outputs are suited to audio playback paths in consumer, communications, and embedded audio systems. The verified data identifies three headline characteristics: 24-bit resolution, support for operation up to 192 kHz, and an 8-pin SOIC package. These values position the converter for designs requiring higher-resolution digital audio and a compact surface-mount footprint. The serial interface and stereo output architecture allow a digital audio source to feed two analog channels through one converter IC. The WM8762CGED family is identified in distributor listings as a Wolfson/Cirrus Logic audio DAC. Its practical implementation depends on the host audio interface, clocking scheme, analog output network, supply arrangement, and the format expected by the connected digital source. Exact pin names, voltage ratings, output architecture, and supported digital audio formats require confirmation from the manufacturer datasheet before PCB or firmware design. Typical audio uses include digital audio players, multimedia systems, communications equipment, and embedded sound-control platforms. In a player design, the converter would typically sit between the digital audio processor and an analog output stage feeding headphones or a line-input amplifier. The compact SOIC package can simplify routing where a small surface-mount footprint is important. Designers should verify the datasheet pinout, recommended decoupling, clock requirements, analog output connection, and supported operating conditions. Since the supplied data does not state supply voltage, pin functions, output mode, or digital interface details, those values are intentionally marked as data needed rather than inferred. This page separates verified distributor facts from engineering information that still requires datasheet confirmation. This page consolidates verified distributor references, package identity, audio-resolution information, and selection guidance. It does not treat generic cross-reference results as proof of drop-in replacement; engineering equivalence must be confirmed by package, pinout, electrical limits, and digital-interface compatibility.

It is designed for multichannel audio systems requiring multiple synchronized analog outputs. An audio DAC is a data-conversion IC that transforms digital audio samples into corresponding analog voltage signals. In the broader hierarchy, the WM8766GEDS/V is a digital-to-analog converter within the ADC/DAC family of data-converter and signal-conversion integrated circuits. Such devices are commonly positioned between an audio processor and an analog amplification or speaker-output stage, where they translate I2S or DSP data into left, right, and additional multichannel outputs. The principal features of the WM8766GEDS/V include six DAC channels, 24-bit resolution, a maximum sampling rate of 192 kHz, and support for both I2S and DSP serial interfaces. Its 2.7 V to 5.5 V operating supply supports integration with conventional consumer and embedded audio equipment. The 28-pin SSOP package also provides a surface-mount format suitable for automated PCB assembly, although its lead pitch is finer than that of a standard SOIC package. The converter architecture is intended for high-resolution multichannel playback rather than general-purpose signal generation. A 24-bit data path allows the source system to preserve a larger amplitude-resolution range than lower-resolution converters, while operation at 192 kHz supports high-rate digital audio streams. The available I2S interface is useful for standard audio links between a digital signal processor and the DAC, while DSP interface support provides a framed alternative for compatible source components. Typical applications include DVD and home-cinema surround-sound systems, multichannel hi-fi equipment, automotive audio products, and other audiovisual equipment requiring several synchronized DAC outputs. The six-channel architecture is particularly appropriate when left, right, center, surround, and additional playback channels must be generated from one converter package. Designers should confirm the supported clock, audio-interface, supply, and output configuration against the manufacturer datasheet before layout. The 28-pin SSOP footprint requires a land pattern tailored to its 0.65 mm lead pitch, and analog and digital supply routing should follow the decoupling and grounding recommendations in the Cirrus Logic documentation. Pin assignments, output-mode options, and electrical limits must be checked for the selected board revision. This product record combines the verified WM8766GEDS/V channel count, resolution, sampling rate, interface, supply, package, temperature, and lifecycle information with practical integration guidance. It also distinguishes verified drop-in replacements from related Cirrus Logic family members that may differ in temperature grade, order code, or electrical configuration.

In the signal-chain hierarchy, it belongs to the digital-to-analog converter category, within ADC/DAC converters and data-converter integrated circuits. Such converters translate digital audio samples into analog voltage signals that drive speakers, headphones, amplifiers, or other analog audio stages. The eight-channel architecture is useful when one system must support several simultaneous audio outputs rather than requiring a separate single-channel converter for each output. The verified distributor descriptions identify the WM8768GEDS/V as an audio DAC with 24-bit resolution, 192kHz maximum sampling capability, DSP processing, I2S connectivity, volume control, and 103dB dynamic range as stated by Mouser. It also identifies the physical format as a 28-pin SSOP. These characteristics make the converter suitable for high-fidelity multichannel playback, receiver and amplifier designs, automotive audio systems, and other applications requiring multiple digital audio channels. The digital interface and integrated DSP distinguish the WM8768 from a simple parallel DAC. I2S is commonly used to connect digital audio sources to converters, while on-chip signal processing and volume control reduce the amount of external processing required for channel management and gain adjustment. The available source material does not provide a complete electrical description of the DSP filters, clocks, output architecture, analog supply limits, or digital I/O levels; these details must therefore be confirmed in the manufacturer datasheet before schematic capture. A typical design would accept I2S audio from a source processor, configure the converter for the desired channel map and sample rate, and route the analog outputs toward line-level amplification. Decoupling and output filtering must follow the manufacturer reference circuit. Because the verified data does not include capacitor values or a full pin assignment, engineers should not infer those values from generic audio guidance. The WM8768GEDS/V is appropriate when the design needs an integrated eight-channel, high-resolution audio DAC rather than a low-channel-count codec. It is also relevant to CD, DVD, home theater, automotive infotainment, and powered-speaker systems, provided the system clocking, supported sample-rate configuration, and analog output topology match the finished board. Current distributor listings show the part available through major electronics distributors, while detailed pricing and lifecycle terms should be checked against live inventory. This page consolidates the verified 24-bit, 192kHz, eight-channel, DSP, I2S, volume-control, 103dB, and SSOP-28 facts while separating confirmed data from missing technical details. It also identifies same-family alternatives and provides practical design cautions for clocking, filtering, grounding, and supply decoupling without inventing unverified component values.

Designers should verify the WM8775SEDS/V pinout, analog input configuration, clocking requirements, digital interface timing, supply recommendations, and decoupling requirements against the manufacturer datasheet before layout. Because the available verified material is primarily distributor and indexed-datasheet information rather than a complete numerical electrical table, unspecified values are marked as [DATA_NEEDED] rather than inferred. The SSOP footprint also requires attention to thermal performance, lead spacing, soldering profile, and analog signal routing. This page combines verified distributor identification, datasheet indexing, package information, application context, comparison structure, and engineering design guidance. It distinguishes documented facts from parameters that require confirmation in the official WM8775 datasheet, helping engineers identify the correct 24-bit, 96 kHz multiplexed stereo ADC without relying on unsupported assumptions.

A clock derived from the incoming S/PDIF signal can support system synchronization, while the transmit path provides S/PDIF output from a compatible digital audio source. The combination of integrated PLL functions and clock output reduces the amount of external clock-generation circuitry required in consumer audio products. Typical applications include digital home-theater equipment, CD and DVD player subsystems, digital audio receiver boards, active speaker interfaces, consumer home-audio products, and industrial digital audio equipment. The 20-lead SSOP package supports compact circuit layouts, although its larger lead pitch and body dimensions should be considered against smaller surface-mount alternatives when space is constrained. Designers should provide a clean and stable 2.7 V to 3.6 V supply, route the S/PDIF data and clock signals away from noisy switching nodes, and ensure the selected master-clock source has adequate low-jitter performance. Decoupling and exposed-ground layout should follow the manufacturer datasheet recommendations, particularly when the transceiver is adjacent to a switching power supply or a high-speed digital processor. This product summary consolidates the verified distributor specifications, manufacturer-oriented datasheet references, package information, and design considerations into one engineering-focused guide. It also distinguishes documented electrical facts from unavailable pricing, lifecycle, pin-level, and equivalent-part information so engineers can assess fit without relying on unverified substitutions.

It supports sampling rates from 8 kS/s to 48 kS/s and is housed in a compact 28-W-CSP measuring 2.59 mm by 2.50 mm. The device operates from a 1.71 V to 3.6 V supply and is intended for space-constrained audio capture and voice-recording systems. An audio ADC is a mixed-signal semiconductor that converts an analog microphone or line-level waveform into a digital audio stream. The WM8952ECS/RV belongs to the audio ADC hierarchy, combining an analog-to-digital converter, programmable gain stage, microphone preamplifier, and digital filters into one package. This integration reduces the number of discrete signal-conditioning components required near a microphone capsule or audio input while preserving a standard digital interface for downstream processing. The converter provides 24-bit resolution and supports sampling rates extending to 48 kS/s. Its signal path includes a selectable high-pass filter and four fully programmable notch filters. A mixed-signal automatic level control function with noise gate helps maintain usable recording levels, and the PGA gain can be read back while ALC operation is active. These features are useful in microphone arrays, voice-capture products, and compact consumer audio equipment where environmental noise and changing source levels require active signal conditioning. The digital audio interface supports I2S as well as A-law and μ-law formats. I2S provides a framed, clocked connection to a digital audio processor, host controller, or audio codec, while the companded formats support legacy telephony and voice applications. The manufacturer datasheet describes the device as using an advanced sigma-delta converter design to provide high-quality audio across its 8 kS/s to 48 kS/s operating range. Typical uses include digital voice recorders, headset electronics, mobile audio accessories, microphone preamp modules, and compact industrial monitoring equipment. Its 28-W-CSP footprint is particularly useful when board area is restricted, although careful escape routing and stable analog supply design remain essential because the device combines sensitive analog input circuitry with a high-speed digital interface. Designers should treat the microphone input, digital clock lines, and supply connections as separate critical paths. Keep analog traces short, use a clean low-noise supply, and follow the manufacturer’s recommended application circuit and component values. The 1.71 V to 3.6 V operating range also requires the host system to remain compatible with the converter’s supply and I2S logic levels. This product page combines the manufacturer specifications, verified distributor listings, package information, application guidance, and replacement analysis for engineers evaluating the WM8952ECS/RV. It also distinguishes documented device functions from specifications that require confirmation from the full datasheet, helping designers plan microphone-front-end integration, interface compatibility, and board-level sourcing.

Typical uses include mobile-handset voice capture, digital voice recorders, headset microphones, portable audio accessories, stereo line-input equipment, and compact consumer devices that accept digital audio from the WM8953ECS/RV. The same integrated conversion and clocking architecture also suits industrial monitoring modules when power consumption, package area, and audio input count are important constraints. Design the analog input network for the intended source impedance and signal amplitude. Keep microphone and line-input traces short, isolate them from switching nodes, place filtering capacitors close to their associated pins, and maintain a continuous ground reference beneath the analog section. The compact 42-WLCSP requires careful assembly planning because its fine-pitch land pattern and exposed thermal area demand accurate stencil, paste, and reflow control. This product page combines the WM8953ECS/RV device identity, interface and conversion details, application guidance, design considerations, sourcing options, and verified manufacturer information to support engineering selection and PCB planning.

Cirrus Logic markets the device for portable audio applications where several audio functions must share a small circuit area. An audio DAC is a mixed-signal integrated circuit that converts digital audio samples into analog voltage signals for amplifiers, headphones, or loudspeakers. Within the broader signal-chain hierarchy, the WM8955LSEFL combines a digital-to-analog converter, digital signal processing, clock generation, and output-driver functions. Integrating these blocks reduces the component count and board area required around a portable device's audio output stage. Key device attributes include two output channels, 24-bit resolution, and a 48 kSPS audio sampling rate listed for the WM8955LSEFL. The manufacturer also identifies DSP and I2S interfaces, along with separate analog and digital supply domains. A related WM8955LSEFL/R variant is described as supporting a 96 kSPS sampling rate, demonstrating the family's capability for higher-rate digital audio transmission. The integrated digital processing and PLL allow the converter to derive the required audio clock from a system reference and support multiple serial audio formats. The manufacturer lists DSP and I2S as the principal data interfaces, making the device suitable for application processors and portable audio hosts that provide digital sample streams. Its low-voltage operation suits battery-powered equipment where analog and digital rails commonly sit between 1.8 V and 3.3 V. Typical uses include portable media players, smartphones, tablets, digital audio accessories, and compact consumer products. The WM8955LSEFL can also serve as the output stage in a portable speaker system, reducing the need for separate analog codec and output-amplifier blocks. System designers should confirm the selected host interface, required sampling rate, output configuration, and load impedance against the manufacturer datasheet before releasing a PCB. A key design consideration is the relationship between supply voltage, output drive, and thermal dissipation. Headphone and speaker outputs dissipate power as voltage drop across the output transistors, so sustained high-level playback can raise junction temperature even though the digital interface consumes comparatively little power. Reserve copper around the exposed pad, follow the manufacturer's layout guidance, and place output protection components where they cannot compromise the intended load drive. This page consolidates device specifications, interface details, application guidance, and component-selection considerations for engineers evaluating the WM8955LSEFL in compact audio systems.

The Cirrus Logic WM8960CGEFL/RV is a stereo audio codec with integrated Class-D speaker drivers, headphone drivers, and a microphone interface, designed for portable digital audio applications. The device is identified as a 24-bit stereo audio interface in a 32-QFN package measuring 5 x 5 mm, and the verified manufacturer-related data states that it provides 1 W per channel into 8-ohm loads with a 5 V supply. Its combination of digital audio conversion, analog input, headphone output, and integrated speaker amplification allows portable equipment to use one compact audio subsystem instead of separate codec and amplifier packages. A stereo audio codec is an interface IC that converts digital audio data into analog signals and converts analog microphone or line-level inputs back into digital audio data. The WM8960CGEFL/RV belongs to the broader audio interface and power-management hierarchy: audio codec, mixed-signal interface IC, semiconductor, and portable-audio signal-chain component. Its integrated Class-D speaker drivers target compact speaker solutions where PCB area, component count, and low power are important. The headphone drivers support personal-audio outputs, while the microphone interface supports portable voice and communication functions. Verified source data identifies the part as a stereo CODEC with 1 W stereo Class-D speaker drivers and headphone drivers for portable audio applications. The supplied DigiKey result identifies it as a 24-bit stereo audio interface in a 32-QFN 5 x 5 mm package. The WM8960CGEFL/RV is therefore suited to portable audio systems where the digital host interface, analog audio paths, and speaker amplification must coexist in one package. The exact sample rate, voltage range, control interface, and full pin-level electrical limits are not included in the supplied verified data and must be confirmed from the manufacturer datasheet before design release. A key design consideration is analog and power-supply layout. Digital audio clocks and control signals should be kept away from sensitive microphone and headphone paths, while the integrated speaker outputs require careful return-current routing and adequate power delivery. Decoupling must follow the manufacturer’s recommended values and placement because the codec combines digital, analog, headphone, and Class-D output functions in one package. Designers should also verify speaker impedance, load current, thermal conditions, and supply sequencing against the official datasheet before connecting external transducers. Typical uses include portable media players, compact audio accessories, personal-audio products, voice-enabled devices, and small speaker systems.

The Cirrus Logic WM8962ECS/R is a 24-bit stereo audio codec with I2C and SPI control in a 49-ball WLCSP measuring 3.59 mm by 3.98 mm. The device combines a 98 dB ADC, a 94 dB DAC, and an integrated Class-W headphone amplifier, making it suitable for compact audio products that need high-resolution conversion and efficient headphone drive. An audio codec is an integrated circuit that converts digital audio data into analog signals and analog audio inputs into digital PCM data. It sits between a digital audio host, such as a microprocessor or application processor, and external audio transducers. A typical stereo codec also integrates programmable gain, filters, headphone-output circuitry, and a digital control interface to reduce the number of discrete components required in portable equipment. The WM8962ECS/R provides a 24-bit stereo interface and supports both I2C and SPI control. Its verified 98 dB ADC and 94 dB DAC figures establish the advertised dynamic-range performance for the conversion sections. The ultra-low-power codec architecture targets battery-powered audio equipment where conversion performance, standby consumption, and board area are all important constraints. Its integrated charge pump creates a ground-referenced headphone output, eliminating the need for DC-blocking capacitors on the headphone outputs. The design also uses Cirrus Logic Class-W amplifier techniques and a dual-mode charge-pump architecture to optimize efficiency and power consumption during playback. A DC servo reduces output ground offsets, improving headphone-output behavior and simplifying the external signal path. Typical uses include smartphone and tablet audio paths, portable media players, connected audio accessories, digital personal audio devices, and compact consumer equipment with analog headphone outputs. The combination of a 49-ball WLCSP, integrated stereo converters, flexible digital control, and capacitor-free headphone outputs is especially useful when PCB area is constrained. Designers should verify the complete pin assignment, exposed-ball configuration, supported digital audio formats, clocking requirements, and analog routing against the manufacturer datasheet before layout. Decoupling, analog grounding, headphone routing, and charge-pump layout remain critical because this highly integrated device combines sensitive converters, digital interfaces, and switching amplification on one small package. This page combines verified distributor availability, exact package information, converter-performance figures, and manufacturer-described charge-pump and Class-W features.

Cirrus Logic WM8998ECS/R is a 24-bit HD audio hub and SLIMbus audio interface housed in a 117-WCSP package measuring 5.35 mm by 4.09 mm. The verified distributor records identify the device as a Hi-Fi coding-switch solution intended for compact digital audio systems. Its interface orientation makes it suitable for products that require a low-power, highly integrated audio front end while retaining a digital audio link to a host processor. An audio codec is an integrated circuit that converts digital audio data into an analog output and converts analog microphone or line inputs back into digital data. In the product hierarchy, a codec is an audio interface IC within the broader class of interface ICs. The WM8998ECS/R is positioned for portable and embedded audio functions where component count, board area, and host connectivity are important design constraints. The verified product listing specifically identifies a 24-bit HD audio interface, SLIMbus connectivity, and a 117-WCSP package. These confirmed attributes make the part relevant to smartphone, tablet, portable-media, headset, and embedded-audio designs. The 5.35 mm by 4.09 mm package reduces board footprint, although its 117-ball construction requires careful assembly, inspection, and PCB-layout planning. Technical evaluation must be completed against the manufacturer datasheet because the supplied distributor results do not expose the complete electrical tables. Sample rate coverage, supported clock rates, microphone bias, codec specifications, digital levels, power-supply requirements, and thermal limits are not available in the verified data and therefore cannot be safely inferred. Designers should also confirm the exact exposed-pad, ball-map, and recommended-land-pattern details before layout release. Typical implementation places the WM8998ECS/R between one or more analog audio transducers and a digital audio host connected through SLIMbus. Its integrated hub role can simplify system routing in devices containing speaker, headphone, microphone, and line-level audio paths. The correct external amplifiers, passive network, clocking, and decoupling must be selected from the manufacturer reference design rather than inferred from the distributor summaries. The primary design consideration is PCB implementation. A 117-WCSP package has a much denser interconnect than a conventional leaded package and can create soldering, inspection, and repair challenges. Confirm whether the assembled board will use optical inspection or X-ray inspection, and use the manufacturer-approved footprint and reflow profile to reduce assembly defects. The verified data does not expose pin names, so a complete ball assignment cannot be published here. This product record combines verified distributor pricing, package information, sourcing links, and engineering-oriented selection guidance. It also separates confirmed facts from unavailable datasheet parameters and avoids presenting generic codec specifications as facts about the WM8998ECS/R.

WM9001GEFL - 1W Class AB/D Speaker Driver | Cirrus Logic

The Cirrus Logic WM9001GEFL is a 1 W mono dual-mode Class AB and Class D speaker driver packaged in a 16-pin QFN with an exposed pad. The distributor data identifies it as an audio amplifier IC with a 1 W output rating, Class AB and Class D operating modes, and a compact 3 x 3 mm QFN package. These characteristics place it in the speaker-driver hierarchy of audio amplifier ICs used to drive small electrodynamic transducers. A speaker-driver amplifier is an integrated circuit that accepts an analog audio signal and delivers enough current and voltage to move a miniature speaker cone. The dual-mode architecture gives a system designer the option to select Class AB behavior for linear output or Class D behavior for higher conversion efficiency. The WM9001GEFL is therefore positioned for compact audio products where speaker output, board area, and energy consumption must be balanced. The WM9001GEFL's principal verified specifications are its 1 W output capability, single-channel mono configuration, support for both Class AB and Class D amplification, and 16-QFN package with an exposed pad. The exposed pad supports heat transfer from the IC into the printed circuit board. Because no verified voltage, current, frequency-response, distortion, thermal-resistance, or shutdown information was supplied, those values must be confirmed in the manufacturer datasheet before final design release. Technically, this device belongs to the integrated-circuit amplifier family and more specifically to speaker-driver audio ICs. Its 3 x 3 mm QFN package supports high-density PCB layouts but demands careful control of exposed-pad soldering, copper thermal paths, and acoustic-mechanical layout. Class AB and Class D modes can also differ in EMI behavior and power efficiency, so mode selection should be based on the complete analog path, speaker impedance, and enclosure conditions rather than package size alone. Typical uses include portable-device speakers, compact consumer-audio products, personal-audio accessories, small embedded audio systems, and accessory modules requiring a mono 1 W drive stage. In these applications, the device can sit near the speaker connector to shorten the high-current output path, reduce load-related board losses, and simplify the analog architecture. Designers should still validate output power at the intended speaker impedance and frequency range. The primary design consideration is thermal management. Although the package includes an exposed pad, continuous Class AB output near the 1 W rating can dissipate more power than Class D operation. The pad should be connected to a suitable ground plane and thermal copper area, while input, feedback, and output routing should avoid the loudspeaker return path. Decoupling and output-filter values must come from the manufacturer application guidance. This product record consolidates verified distributor inventory, package information, source links, engineering caveats, and selection guidance that are not consolidated on a typical distributor listing. Where the supplied evidence does not establish a parameter or a true pin-compatible substitute, the record explicitly marks the gap rather than presenting an unsupported value.

The Cirrus Logic WM9081GICN/V is a mono 24-bit digital-to-analog converter with an integrated 2.6 W Class AB/Class D speaker amplifier, supplied in a 28-pin QFN package measuring 4 x 4 mm. It accepts I2S, DSP, LJ, and RJ digital audio data and is intended for space-constrained portable equipment where a single device must provide high-resolution digital-to-analog conversion and speaker drive. The operating voltage range is 1.71 V to 3.6 V, and the specified temperature range is -40 °C to +85 °C. An audio DAC converts digital audio samples into an analog voltage signal suitable for an audio amplifier or speaker driver. The WM9081GICN/V combines that conversion function with a programmable output stage and integrated mobile parametric equalization. Its fully programmable EQ coefficients allow speaker and enclosure characteristics to be optimized, while programmable dynamic-range control supports louder playback at low listening levels. The result is a compact audio signal-chain component that reduces the need for separate DAC and speaker-driver packages. The device supports 2-wire, 3-wire, 4-wire, and hardware control modes, with digital audio formats including LJ, RJ, I2S, and DSP. TDM support broadens its usefulness in multi-channel portable audio systems where several codec or converter functions share one digital bus. A thermal-shutdown interrupt provides a system-level indication that the integrated output stage has entered its protected operating condition. The manufacturer also identifies programmable gain as part of the device feature set. Typical applications include portable media players, mobile phones, compact personal audio systems, docking speakers, and other battery-powered products with an integrated single-speaker output. Placing the DAC and amplifier in one package reduces board area, external component count, and the number of signal connections between the digital audio source and the speaker. Design layouts should follow the manufacturer datasheet for decoupling, exposed-pad grounding, and analog output routing. Keep the digital interface traces away from the speaker output and amplifier supply nodes to reduce the chance of switching-edge coupling into the audio path. Confirm the configured control mode and digital format in firmware before enabling the output stage. This page organizes the WM9081GICN/V specifications, application guidance, package details, and sourcing information into a single engineering reference for compact mono audio output designs.

The device operates from a 2.7 V to 5.5 V supply and is intended for compact low-power audio systems. An audio amplifier is an integrated circuit that converts an input audio signal into sufficient output power to drive a loudspeaker or other transducer. Class AB amplifiers provide linear operation with comparatively continuous output current, while Class D amplifiers switch the output stage to improve power-conversion efficiency. The WM9094ECS/R supports both operating modes, giving designers flexibility according to their efficiency, distortion, and thermal requirements. Key features include Class D and Class AB output capability, a 2 W maximum output-power rating into 4 ohms, integrated depop circuitry, integrated thermal protection, and a surface-mount 20-WCSP package. The 2.7 V minimum supply voltage supports portable and space-constrained equipment, while the 5.5 V maximum supply voltage accommodates common low-voltage power rails. The WM9094ECS/R is identified as a mono, one-channel amplifier rather than a multi-channel power amplifier. Its compact 2.53 mm by 2.07 mm package can reduce board area in mobile accessories, personal-audio products, and other integrated audio equipment. The manufacturer and distributor listings identify it as an ultra-low-power audio subsystem and list the part as obsolete. Typical applications include compact speaker systems, portable audio accessories, and low-voltage embedded products where a single amplified channel is sufficient. System-level implementation must account for the 2.7 V to 5.5 V supply range, speaker impedance, output power, thermal conditions, and the small-area land-pattern requirements of the 20-WCSP package. The principal design consideration is the obsolete lifecycle status. Designers should verify availability, source quality, and long-term supply before committing to a new production design. For a new design with obsolete risk, engineers may need to qualify an alternative rather than assume that any Class D or Class AB amplifier is pin compatible. This page consolidates the verified distributor specifications, lifecycle information, package details, sourcing links, practical application guidance, and an explicit assessment of replacement availability. It also separates documented parameters from missing technical data instead of presenting unverified electrical characteristics as guaranteed specifications.

WM9701CPT Stereo Audio Codec | Texas Instruments

The Texas Instruments WM9701CPT is a stereo audio codec with an integrated analog audio channel and digital audio interface, supplied in a 28-pin TQFP package. The verified distributor data identifies it as an Audio Special Purpose / Audio Channel device and lists an LCSC starting price of $0.6762. Its primary role is converting digital audio data into analog stereo signals while supporting audio-system signal conditioning and analog output control. The package designation CPT identifies a 28-pin TQFP-compatible physical format, but detailed electrical limits, supported sample rates, interface modes, analog performance, and pin functions are not present in the supplied verification records. A codec is an audio interface integrated circuit that combines digital-to-analog conversion, analog signal paths, and control or communication functions. In the broader semiconductor hierarchy, an audio codec belongs to an audio interface IC, then to an interface IC and a mixed-signal semiconductor. This integration can reduce the number of separate converters and support components in consumer audio, communications, and embedded systems. For the WM9701CPT, however, the supplied data does not establish whether its digital interface is I2C, I2S, or another format, nor does it quantify the number of supported channels. The verified records provide three useful procurement anchors: DigiKey Marketplace lists WM9701CPT for purchase and shipment, Octopart identifies availability and pricing across two distributors, and LCSC lists the part as in stock from $0.6762. A separate distributor listing describes the device as an analog consumer audio/video IC. These sources support commercial availability, but they do not provide manufacturer lifecycle status, operating temperature, supply voltage, clock requirements, DAC resolution, SNR, THD, output impedance, or pin-level mapping. WM9701CPT is best evaluated as a legacy or inventory-dependent audio codec rather than assumed to be a currently designed modern USB audio solution. Before schematic release, an engineer should obtain the original manufacturer datasheet and confirm the CPT land pattern, exposed-pad requirements, digital interface, analog routing, clocking, and firmware or register expectations. The part number alone is not enough to establish drop-in compatibility or modernization safety. Potential audio applications include legacy consumer-audio systems, portable media equipment, communications terminals, and embedded products that already target this codec family. Such uses remain conditional because the supplied data does not verify operating conditions or signal paths. Component selection should be based on a complete datasheet review rather than the distributor category label. The main engineering risk is assuming that similarly named stereo codecs are interchangeable. Digital-interface timing, register maps, analog routing, package dimensions, exposed-pad treatment, and software initialization can differ even when the functional description is similar. Validate the replacement against the original schematic and PCB footprint before committing to an alternative. This page consolidates the verified distributor listings, separates confirmed procurement facts from missing technical data, and avoids inventing specifications, pin assignments, or drop-in replacements.

WPC8763LDG - Embedded Controller IC QFP-128 | Winbond

The Winbond Electronics WPC8763LDG is a specialized embedded controller (EC) integrated circuit supplied in a 128-pin QFP surface-mount package, designed primarily for notebook PC and mobile-system platform management applications such as keyboard scanning, power sequencing supervision, and thermal/fan control. An embedded controller is a specialized microcontroller that operates semi-independently of the host CPU to manage low-level platform functions. In the PC system hierarchy, the EC sits below the main CPU and chipset (PCH) as a power-management IC tier: it handles keyboard matrix scanning, battery charging supervision, thermal monitoring, fan speed control, and lid/power-button events, typically following Intel or AMD platform EC firmware specifications such as those used with ACPI and eSPI/KBC interfaces. The WPC8763LDG belongs to Winbond's WPC876x family of embedded controllers, which integrates an 8-bit or proprietary MCU core with on-chip flash/ROM program memory, keyboard controller (KBC) logic, GPIO, PWM channels for fan control, and ADC inputs for thermal and voltage monitoring. Key differentiating features of this family include the high GPIO count required for notebook keyboard matrices, integrated PWM fan controllers that reduce external component count, and low standby power consumption for battery-operated systems. The 128-pin QFP package provides sufficient I/O for a full notebook EC implementation on a single chip. Architecturally, EC devices like the WPC8763LDG combine a low-power MCU core, a shared RAM region, dedicated peripheral blocks (PS/2 keyboard interface, SMBus/I2C masters for battery and thermal IC communication, pulse-width modulators, and watchdog timers), and boot ROM. Firmware executes from internal non-volatile memory, and the EC communicates with the chipset over LPC or eSPI buses depending on platform generation. Typical applications include laptop and notebook motherboard EC functions, keyboard/mouse controller emulation (PS/2 KBC/Mouse), battery charging management in coordination with a charger IC, thermal and acoustic (fan) management, and general-purpose GPIO expansion in portable and industrial embedded systems. A key design consideration is firmware compatibility: the EC must run BIOS-coordinated firmware, so replacing this device requires both hardware pin compatibility and firmware/toolchain support - verify code image compatibility before any substitution.
