WM8728SEDS/V - 24-Bit Stereo DAC | Cirrus Logic

The Cirrus Logic WM8728SEDS/V is a 24-bit, 192 kHz stereo digital-to-analog converter with integrated volume control, I2S digital audio input, and a 20-pin SSOP package. It converts two digital audio channels into balanced or unbalanced analog outputs, making it suitable for audio equipment that requires high-resolution playback and a compact mixed-signal footprint. A stereo DAC is an audio interface that accepts digital PCM samples and reconstructs the corresponding left- and right-channel analog waveforms. In the product hierarchy, a DAC belongs to the ADC/DAC class of data-conversion integrated circuits and supports the broader audio-processing chain. The WM8728SEDS/V combines digital audio input, volume control, and analog output stages in one package, reducing the number of external components required in compact audio products. The converter supports 24-bit digital audio operation at sample rates up to 192 kHz. Its integrated volume control provides a convenient way to adjust playback gain without implementing a separate analog attenuation circuit. The I2S-compatible interface connects to digital audio processors, USB audio bridges, portable media systems, and home-audio equipment, while the 20-pin SSOP package supports conventional surface-mount assembly. System partitioning is especially important for this converter. Digital audio data enters through the serial interface, while the analog section reconstructs left- and right-channel signals at the converter output. Correct synchronization between the audio processor and the DAC is essential for preventing clicks, repeated samples, or channel misalignment. Power, ground, and analog-output routing must be arranged to minimize noise coupling into the reconstructed waveform. Typical uses include digital active speakers, compact stereo amplifiers, USB audio equipment, portable audio products, and embedded playback systems. The 192 kHz capability makes the device appropriate for high-resolution audio paths, while the integrated volume control simplifies signal-chain design. The same device can support headphone, line-level, or other analog stages when its output configuration and external network are matched to the intended load. The primary design trade-off is integration versus implementation flexibility. Integrated volume control reduces external circuitry and helps simplify control software, but an adjustable external analog amplifier may provide wider gain control or additional filtering. Before finalizing the layout, consult the manufacturer datasheet for the exact output-mode pins, recommended capacitors, supported clocking arrangements, and analog output configuration. This product summary consolidates the exact resolution, sample-rate, interface, channel, packaging, and volume-control characteristics into an engineering-focused selection guide. It also distinguishes the WM8728SEDS/V from the identified WM8728SEDS-RV option and provides design notes covering clocking, grounding, filtering, output loading, and thermal verification for dependable stereo audio implementation.

The WM8738CGED is intended for audio capture, conversion, and signal-chain designs where a compact package, stereo conversion, and a 96 kHz maximum sampling rate are the principal selection criteria. An ADC, or analog-to-digital converter, is an integrated circuit that samples an analog audio voltage and converts it into a digital representation. A stereo ADC processes two audio channels, which allows left and right microphone, line, or other analog sources to be captured simultaneously. Digital audio words are then transferred to a processor, digital signal processor, or audio codec using a serial interface such as I2S. The WM8738CGED therefore occupies the boundary between the analog input stage and the digital audio processing stage. According to the verified DigiKey and Mouser product listings, the key device parameters are 24-bit conversion, operation up to 96 kHz, stereo ADC operation, I2S support, and a 14-SOIC package. The 24-bit resolution provides a nominal 16,777,216 quantization levels per channel, while 96 kHz supports the conversion rate required by many CD-rate and higher-rate audio systems. These figures make the part applicable to consumer audio, communications, multimedia, and embedded audio-conversion equipment. The 14-SOIC package is mechanically compact relative to many older through-hole audio converters and is suitable for conventional surface-mount PCB assembly. Its small pin count should be evaluated carefully in designs requiring multiple analog inputs, auxiliary digital functions, or extensive filtering. The verified distributor data does not expose the complete input topology, clocking architecture, analog reference arrangement, or auxiliary interface implementation, so those details should be confirmed in the manufacturer datasheet before layout is released. For implementation, the analog input path, grounding, and clocking integrity are the decisive engineering areas. Short, symmetrical analog traces, adequate bypass capacitors, and a clean source of digital audio clock signals help preserve converter performance. Designers should also verify supported master and slave clock configurations, input coupling requirements, and the required logical control sequence against the official datasheet. This page consolidates verified distributor specifications, source links, and drop-in replacement information for the Cirrus Logic WM8738CGED. It also separates confirmed parameters from values that still require the manufacturer datasheet, preventing unverified electrical, pinout, and compliance claims from being presented as established facts.

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 integrates digital audio interfaces, analog audio conversion, and codec control into a single device for multichannel consumer audio equipment. An audio codec is a mixed-signal semiconductor that converts digital audio data into analog signals and, in some designs, converts analog input into a digital stream. A codec sits within the broader audio interface hierarchy and connects a digital audio bus, analog output circuitry, clocks, control logic, and sometimes microphone inputs. The WM8860GEFL/V is therefore positioned between an HDA controller and the analog speaker or headphone output stage of a finished audio system. The WM8860 family provides two high-performance stereo DACs, enabling four channels of high-definition audio from one package. Its 32-bit audio interface and HDA revision 1.0 compatibility allow it to operate with industry-standard HDA controllers. The 48-QFN package supports compact integration in consumer electronics while providing the mixed-signal connections required for digital audio routing, analog outputs, and codec configuration. The device uses a registered I2C-style control interface and supports vendor-specific control verbs in addition to the standardized HDA verbs implemented by the WM8860. Its system-level role depends on correct clock generation, I2C address configuration, firmware initialization, output-path routing, and analog implementation. These controls allow a host controller to configure playback paths, mixer behavior, and digital volume while the integrated DACs generate the final analog audio channels. Typical applications include desktop computers, home-theater equipment, multichannel active speakers, game consoles, audio docking stations, and consumer media systems with Intel HDA-compatible controllers. It is particularly appropriate where four analog output channels are required without using multiple separate codec packages. System-level audio performance still depends on the external clock source, power supplies, analog output network, grounding, and speaker or headphone amplifiers connected downstream. Design the 7 mm by 7 mm footprint with thermal-via access beneath the exposed pad and keep sensitive analog routing away from digital clocks and switching supply nodes. Validate every external component value against the manufacturer reference schematic and recommended layout. The MPN suffix identifies a specific orderable configuration, so board releases should confirm the full WM8860GEFL/V designation rather than relying only on the WM8860 family name. This page consolidates the verified package, interface, channel-count, and HDA-compatibility details, adds application-specific engineering guidance, and separates confirmed characteristics from parameters that must be confirmed in the manufacturer datasheet before schematic release.

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.
