WM8775SEDS/V 24-Bit 96kHz Stereo ADC | Cirrus Logic
MPN: WM8775SEDS/V ✗ انتهى عمره الإنتاجيWM8775SEDS/V نظرة عامة
An audio ADC is an integrated circuit that converts analog audio voltages into a digital representation for processing, storage, transmission, or playback. The WM8775 belongs to the broader ADC and DAC product category, specifically a multiplexed stereo audio ADC. Its four-channel input mixer allows several analog sources to be selected and digitized through the same conversion engine, reducing the need for separate converters when a system must process multiple audio inputs.
The primary verified specifications for the WM8775SEDS/V are its 24-bit conversion resolution, 96 kHz sampling capability, stereo ADC architecture, four-channel input multiplexer, I2S digital interface, and 28-pin SSOP package. According to the manufacturer-linked datasheet information in the verified sources, the device is intended for high-performance audio digitization and surround-sound processing applications. The manufacturer datasheet is the authoritative source for detailed electrical limits, clock requirements, analog input ranges, digital timing, recommended application circuits, and package dimensions.
Typical application areas include surround-sound processors, home audio equipment, automotive audio systems, and other audiovisual products that require multiple analog audio inputs to be converted into a digital format. In these systems, the multiplexer can select different source signals while the stereo ADC performs the actual conversion. The I2S interface supports integration with digital audio processors, decoders, receivers, and other equipment using compatible serial audio connections.
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 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.

التطبيقات النموذجية
WM8775SEDS/V مناسب لـ 6 التطبيقs: Home Theater Surround-Sound Processing, Automotive Audio Digitization, Digital Audio Receiver and Preamp, Multichannel Audio Recording Front End, Car Audio Mixer and Source Selector, Surround-Sound Processor Input Stage.
Home Theater Surround-Sound Processing
The WM8775SEDS/V fits home-theater surround-sound processing because it combines a four-channel analog input multiplexer with a 24-bit stereo ADC capable of 96 kHz sampling. The multiplexer allows a receiver or preamplifier to select among several analog source paths before digitization, while the I2S interface transports the converted stereo data to a digital sound processor or DAC. According to the indexed manufacturer description, the part is intended for digitizing multiple analog sources for surround-sound processing in home hi-fi and audiovisual equipment. Exact gain, reference, input-range, and clock settings must follow the official datasheet rather than inferred values.

Automotive Audio Digitization
The WM8775SEDS/V can support analog-to-digital conversion in automotive audio systems because the WM8775 family is identified for automotive audiovisual equipment. Its four-channel multiplexer helps consolidate multiple source selections, and its 24-bit, 96 kHz conversion capability supports high-resolution source digitization before processing or playback. The verified material does not confirm the exact automotive qualification, temperature range, or lifecycle status of the /V suffix, so those points remain unresolved. A production release should require manufacturer confirmation of the correct grade, environmental tests, supply ratings, and automotive qualification.
موصى به
Digital Audio Receiver and Preamp
The WM8775SEDS/V is suitable for digitizing selected analog inputs in a digital audio receiver or preamplifier. Four multiplexed input channels give the system a practical way to route source audio into one 24-bit stereo conversion path, while the I2S interface connects that path to digital decoding, processing, and output stages. The documented 96 kHz maximum sampling rate supports high-resolution audio use cases. Before layout, engineers should confirm the accepted input impedance, full-scale range, master-clock options, de-emphasis behavior, and channel-routing registers in the manufacturer datasheet.
موصى به
Multichannel Audio Recording Front End
The WM8775SEDS/V can serve in a multichannel audio recording front end when a design must switch among several analog sources and then process the selected stereo pair digitally. The four-channel input multiplexer provides source selection, while the 24-bit, 96 kHz ADC establishes the conversion format. Its I2S output is suitable for connection to compatible digital audio processors, although timing, master-clock generation, and serial-word length must be coordinated with the downstream device. Place analog input routing away from digital clocks and use a quiet reference arrangement according to the official application guidance.
موصى به
Car Audio Mixer and Source Selector
The WM8775SEDS/V can digitize selected source channels in a car-audio mixer or source-selection architecture, where multiple analog inputs must be converted before digital mixing and volume-control processing. Its four-channel multiplexer limits the number of separate converter blocks, and the 24-bit, 96 kHz ADC provides a high-resolution digital representation for the selected stereo pair. The verified data identifies automotive audio as an intended application area but does not confirm qualification for a particular vehicle platform. Verify temperature range, electromagnetic requirements, supply behavior, and automotive grade before production use.
موصى به
Surround-Sound Processor Input Stage
The WM8775SEDS/V is well matched to a surround-sound processor input stage because the verified description specifically identifies four-channel multiplexing for digitizing multiple analog sources. Its stereo ADC converts the selected pair at up to 24-bit resolution and 96 kHz, while I2S provides a conventional digital-audio connection to channel routing, decoding, or mix processing. Compared with using four unrelated converters, the integrated multiplexer can simplify source selection, although channel mapping and gain behavior must be verified from the datasheet. Control software should also account for the exact MUX, gain, and power-up register sequence.

ملاحظات التصميم
Route the four analog inputs and their shared return paths away from the I2S clock, data, and control traces. The verified material confirms a four-channel multiplexer and I2S interface but does not provide routing values, so use the manufacturer's reference layout for component placement. Keep the analog path compact, maintain a continuous ground reference beneath the analog section where the package allows it, and avoid switching-node or high-current return paths beneath the converter.
Place input, output, and bypass capacitors exactly where the manufacturer reference design specifies them. The supplied verified data does not specify capacitor values or stability requirements, so selecting generic values from general ADC practice could alter frequency response, channel matching, or supply-noise rejection. Verify the complete BOM and layout in the official WM8775SEDS datasheet, and preserve the specified capacitor type, voltage rating, and placement tolerance.
Separate and decouple analog and digital supply paths as directed by the manufacturer datasheet. The WM8775SEDS/V converts high-resolution audio, so supply noise can appear as noise in the digital output even when the converter itself operates correctly. Use low-ESR local bypass capacitors, minimize supply-loop area, and confirm sequencing requirements. Supply voltage, current, startup behavior, and permitted operating states are [DATA_NEEDED] in the supplied source data and must not be guessed.
Do not treat WM8775SEDS/R or WM8775SEDS/RV as automatically interchangeable merely because they share the WM8775 family name. Confirm suffix definitions, package tolerances, temperature grade, qualification status, and ordering information in the manufacturer documentation. Also do not copy pin assignments from the WM8772 without checking the WM8775 pin table, because the shared SSOP-28 outline does not by itself prove identical functional pinout across related converters.
