WM8768GEDS/V - 8-Channel 24-Bit 192kHz Audio DAC | Cirrus Logic
MPN: WM8768GEDS/V ✓ AktifWM8768GEDS/V Ringkasan
The WM8768 is a multi-channel audio DAC. 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.

Aplikasi Umum
WM8768GEDS/V cocok untuk 6 aplikasis: Home Theater DAC, Surround-Sound Amplifier, Automotive Infotainment Audio, High-Fidelity Hi-Fi System, DVD and Audio-Video Player, Multi-Zone Audio System.
Home Theater DAC
The WM8768GEDS/V fits home-theater signal chains requiring multiple analog audio outputs from a digital surround-sound source. Its verified eight-channel DAC architecture, 24-bit resolution, and support for operation up to 192kHz provide a suitable converter core for premium amplifiers and active speaker systems. Integrated DSP and volume control can simplify channel management near the output stage, while the I2S interface accepts digital audio from a source or surround processor. The verified description specifically identifies DVD and surround-sound processing as intended applications. Before layout release, engineers must confirm the manufacturer’s channel mapping, master clock requirements, analog output mode, and recommended output filtering in the datasheet.

Surround-Sound Amplifier
The WM8768GEDS/V can provide the multichannel conversion stage of a surround-sound amplifier, converting up to eight digital channels to analog signals for downstream power amplification. Its 24-bit resolution and 192kHz maximum sampling rate suit high-resolution source material, while integrated volume control reduces the need for separate digital gain processing in some architectures. The I2S connection allows the converter to operate behind a digital audio processor or receiver. System partitioning must account for the converter’s unsupported or unverified channel modes, clocking scheme, and output topology. Confirm the exact pin assignment and reference circuit before converting the generic eight-output concept into a production schematic.

Automotive Infotainment Audio
The WM8768GEDS/V is a candidate for automotive infotainment and vehicle audio systems that require multiple decoded audio channels in a limited PCB area. The verified eight-channel DAC and I2S interface can connect a digital audio subsystem to analog amplifier stages for front, rear, and additional zone outputs. Its 192kHz capability provides ample sample-rate headroom for high-resolution source material, although sample-rate support in the complete signal chain must be verified. Automotive deployment also requires checking the supported ambient temperature, supply range, ESD requirements, and qualification status. The supplied sources do not establish AEC-Q100 qualification, so it should not be assumed for safety- or reliability-critical vehicle programs.

High-Fidelity Hi-Fi System
The WM8768GEDS/V is appropriate for a high-fidelity hi-fi design that accepts digital audio over I2S and requires multiple DAC outputs. Its stated 103dB dynamic range provides headroom for low-noise playback, while the 24-bit format and 192kHz capability support high-resolution source formats. The eight-channel configuration can serve multichannel music playback, active speakers, or zone-based amplification, depending on the supported routing model. Analog output filtering, grounding, and channel-to-amplifier routing remain critical to realizing the converter’s performance in a finished system. Because the verified data omits THD+N, output swing, and clock jitter, engineers should evaluate the complete manufacturer specification before using the dynamic-range figure as the sole quality criterion.

DVD and Audio-Video Player
The WM8768GEDS/V can serve as the audio DAC in a DVD player, digital media player, or audio-visual receiver requiring several analog output channels. The verified product description explicitly names DVD and surround-sound processing as target applications, and the eight-channel architecture supports multichannel playback without requiring eight separate converters. I2S provides a conventional digital-audio connection from a decoder or system-on-chip, while DSP and volume control simplify downstream channel administration. The implementation should follow the manufacturer’s reference circuit for decoupling, clock generation, and analog output implementation. Verify whether the intended mode supports all eight outputs simultaneously and whether the selected source device provides compatible clocking and data framing.

Multi-Zone Audio System
The WM8768GEDS/V can support multi-zone audio equipment when separate digital channels must become independent analog outputs. Eight channels may serve listening zones, stereo pairs, or a mix of main and auxiliary outputs, depending on the converter’s supported routing and mixer configuration. Its integrated DSP and volume control are useful for applying channel-specific gain and processing, while I2S simplifies connection to a central audio processor. System planning must ensure that the host supplies the required clocks, data alignment, and supported sample rates for every active channel. The verified information does not describe channel groups, mute behavior, or mixer limitations, so those details must be taken from the datasheet and control software. PCB design should isolate analog outputs from high-current amplifier switching stages.

Catatan Desain
Route the I2S data, clock, and control signals as a compact, continuous digital group away from the eight analog outputs and any class-D switching nodes. The verified material confirms I2S connectivity and an eight-channel DAC but does not provide a reference PCB layout or pinout. Therefore, use the manufacturer layout as the authority for trace geometry, return paths, via transitions, and exposed interface placement rather than relying on generic guidance.
Do not assume that sharing the 28-pin SSOP format proves that every WM8766 or WM8768 suffix is electrically interchangeable. The verified cross-reference listings establish package and broad family relationships, but they do not quantify pin, supply, temperature, or lifecycle differences. Before substituting any listed candidate, compare the manufacturer pin table, supported audio modes, clock requirements, control registers, analog output implementation, and qualification records under the normal change-control process.
The supplied evidence does not provide the WM8768GEDS/V supply-voltage range, recommended capacitor values, power consumption, or startup sequence. Apply the manufacturer’s reference supply network and decoupling arrangement without substituting generic values. Check analog and digital supply routing for adequate separation, keep switching-regulator loops away from the converter outputs, and confirm startup and mute sequencing against the host audio processor requirements.
Treat the master clock, sample clock, and I2S data lines as a matched digital subsystem. The verified data confirms I2S operation and 192kHz capability but supplies no timing budget, input capacitance, trace-length limit, or jitter tolerance. Use short, well-terminated routes, continuous reference planes, and source-synchronous geometry where practical. Validate timing and analog output performance on hardware because no complete application circuit or measured performance data is included.
Do not calculate dissipation for the WM8768GEDS/V without the verified supply voltage, analog output swing, load impedance, and quiescent current. SOA is not applicable because this is an audio converter IC rather than a discrete power semiconductor. During design review, obtain those four operating values from the manufacturer datasheet, then estimate worst-case power and junction temperature with the actual SSOP copper area and nearby amplifier stages.
