WM8786GEDS/V - 24-Bit 192kHz Stereo Audio ADC | Cirrus Logic
N.º da peça: WM8786GEDS/V ✓ AtivoWM8786GEDS/V Visão geral
A stereo audio ADC is a data-conversion IC that accepts two analog audio channels and converts them into digital samples for processing, storage, transmission, or playback. The WM8786GEDS/V belongs to the ADC/DAC and audio data-converter hierarchy, where differential inputs, integrated audio DSP, and a high-resolution serial interface help simplify audio capture designs.
Verified distributor and manufacturer information identifies the WM8786GEDS/V as an audio ADC with 24-bit resolution, operation up to 192kHz, DSP capability, differential inputs, and a 20-SSOP package. The stereo architecture supports simultaneous left and right audio conversion, while the digital audio interface is identified as I2S. These features make the device suitable for consumer audio equipment, recording systems, digital audio equipment, and embedded audio products.
The WM8786GEDS/V is differentiated from general-purpose data converters by its dedicated audio-oriented feature set. Its 24-bit resolution supports high-fidelity capture, the 192kHz maximum sample rate supports high-resolution audio, and differential analog inputs help reduce common-mode noise in balanced audio signal paths. The integrated DSP function can assist with signal conditioning and audio processing, although the exact operating modes and filter settings must be confirmed in the manufacturer datasheet.
Typical applications include stereo recording equipment, consumer audio systems, digital mixing and amplification products, USB or portable audio interfaces, and other systems requiring two-channel audio capture. In these applications, the ADC can be placed between balanced or appropriately conditioned analog audio inputs and an I2S-capable digital audio processor. The 20-SSOP package supports compact PCB layouts, but its fine pitch requires careful soldering and layout practices.
Designers should confirm the analog input range, differential input configuration, reference-voltage requirements, digital supply levels, clocking requirements, and supported I2S formats before releasing a production design. Decoupling capacitors should be placed close to the supply pins, and analog and digital routing should be separated to reduce switching noise coupling into the audio inputs. The manufacturer datasheet and application information should be used for the final input, clock, filtering, and layout implementation.
This product page consolidates verified distributor identity and product descriptions with package, application, selection, and engineering guidance. It distinguishes the WM8786GEDS/V from the related WM8786GEDS/RV ordering variant and provides a practical framework for confirming pin and PCB compatibility before substitution.

Aplicações típicas
WM8786GEDS/V é adequado para 6 aplicaçãos: Stereo Digital Recording, Consumer Audio Equipment, USB Audio Interface, Audio DSP Front End, Portable Audio Capture, Digital Audio Mixer.
Stereo Digital Recording
The WM8786GEDS/V fits stereo digital recording systems that require 24-bit resolution and operation up to 192kHz. Its two differential analog inputs allow the converter to receive left and right audio channels, while the I2S interface transfers digital samples to a recorder, DSP, or storage controller. The differential input architecture is particularly appropriate for balanced audio front ends because it helps reduce common-mode interference. A production design should verify the supported input range, gain structure, reference requirements, clock configuration, and digital timing from the manufacturer datasheet. The 20-SSOP package can support compact designs, although fine-pitch soldering and careful analog-versus-digital partitioning remain important.
Recomendado
Consumer Audio Equipment
The WM8786GEDS/V can be used in consumer audio equipment requiring high-resolution stereo capture rather than a general-purpose low-resolution codec function. Its 24-bit conversion capability and 192kHz maximum sample rate provide headroom for high-fidelity audio paths, while the I2S interface supports connection to digital signal processors and audio engines. The 2.7V to 5.5V operating range can simplify integration with both 3.3V and 5V system architectures, subject to the individual rail requirements in the datasheet. Designers should carefully plan analog input conditioning, clock routing, digital trace isolation, and decoupling to preserve audio performance.
Recomendado
USB Audio Interface
The WM8786GEDS/V is suitable for a USB audio interface architecture in which analog stereo audio is converted before being processed or transmitted by a USB controller. The 24-bit stereo ADC provides a high-resolution front end, and the I2S interface provides a conventional connection to a digital audio processor or USB audio bridge. Differential inputs are useful when the source is balanced, while single-ended sources require an appropriate input conditioning network. Actual USB bandwidth, clock synchronization, and supported sample rates must be coordinated across the complete design. Power and ground partitioning should prevent converter and digital-interface activity from adding noise to the analog capture path.
Recomendado
Audio DSP Front End
The WM8786GEDS/V can serve as the analog-to-digital front end of an audio DSP system. Its stereo differential inputs capture two audio channels, and its integrated DSP feature supports dedicated audio-signal processing before the data is handed to a larger processor over I2S. This arrangement can centralize conversion and signal conditioning while leaving complex filtering, routing, or effects to the downstream digital processor. The 192kHz capability is useful for high-resolution processing, but system designers should confirm that the selected DSP clocking scheme and I2S configuration support the required operating mode. Grounding, reference routing, and analog input layout should follow the manufacturer recommendations.
Recomendado
Portable Audio Capture
The WM8786GEDS/V is compatible with portable audio-capture concepts that require compact stereo conversion and a low-power-friendly supply range. The 20-SSOP package reduces PCB footprint compared with many larger converter packages, while the 2.7V to 5.5V operating range supports multiple embedded supply architectures. The I2S interface allows sampled audio to be transferred to a portable processor for encoding, storage, or wireless transmission. In a battery-powered design, the actual converter and system power consumption must be measured across the selected audio mode. The main implementation risks are fine-pitch assembly, clock jitter sensitivity, and keeping switching circuitry away from the differential audio inputs.
Recomendado
Digital Audio Mixer
The WM8786GEDS/V can be evaluated for a digital audio mixer with stereo analog source inputs and downstream digital processing. Its 24-bit, 192kHz stereo conversion provides a high-resolution capture stage, while differential inputs can support balanced source connections and reduce susceptibility to common-mode noise. The I2S output can feed mixer DSP, routing, and processing logic when the clock and framing formats are matched. Input selection, gain control, and channel routing should be designed around the converter's verified electrical limits. Practical implementation requires short analog traces, stable references, local supply bypass capacitors, and clock lines that avoid digital switching nodes.

Notas de projeto
Route the differential audio inputs as a closely coupled pair and keep them away from switching nodes, clock lines, and high-current output paths. Place input-network components close to the ADC pins where the supported impedance and timing requirements allow, and provide a quiet return path to the device ground reference. The supplied data confirms differential inputs and a 20-SSOP package but does not specify the complete recommended layout, so the manufacturer application guidance should be treated as controlling.
Provide local bypass capacitors at the supply pins and separate analog and digital supply paths where the board architecture permits. The verified operating range is 2.7V to 5.5V, but the exact supply sequencing, reference-voltage, and current requirements are not included in the supplied data. Confirm capacitor values, voltage ratings, and power-distribution topology from the manufacturer datasheet rather than relying on generic regulator-decoupling guidance.
Do not assume that the WM8786GEDS/RV suffix is automatically production-equivalent merely because it has the same core ADC description and 20-SSOP package. The verified search results do not include a complete pin-by-pin comparison. Before substitution, verify pin names, analog input range, reference behavior, clock requirements, I2S framing, electrical limits, exposed thermal conditions, and ordering information with the manufacturer or an authorized supplier.
Treat the converter clock as a signal-quality-critical path. Use short, properly referenced clock routing, avoid unnecessary stubs, and keep clock signals separated from the differential audio inputs. If the I2S source is generated by a noisy digital processor, verify clock jitter and signal integrity at the ADC rather than assuming nominal digital timing is sufficient for 192kHz operation. The supplied data does not state the maximum clock frequency or jitter tolerance.
Informações de conformidade
The supplied verified data identifies the manufacturer, device type, resolution, sample rate, interface, package, input architecture, and supply range, but does not provide compliance statements. These fields remain unknown rather than being inferred.
