WM8766GEDS/V - 24-Bit 6-Channel 192kHz DAC | Cirrus Logic
MPN: WM8766GEDS/V ✓ Hoạt độngWM8766GEDS/V Tóm tắt
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.

Ứng dụng tiêu biểu
WM8766GEDS/V phù hợp cho 6 Áp dụngs: Home Theater and DVD Audio, Multichannel Hi-Fi Receiver, Automotive Audio System, Professional Audio Monitoring, Digital Audio Player, Multichannel Gaming and Media Console.
Home Theater and DVD Audio
The WM8766GEDS/V fits home-theater and DVD audio designs that require several synchronized analog outputs from a digital audio source. Its six 24-bit DAC channels at up to 192 kHz provide ample channel count and resolution for surround-sound playback, while DSP and I2S interfaces support common source-controller architectures. The 2.7 V to 5.5 V supply range suits mixed-voltage equipment designs. Layout must preserve the separation of analog output routing from digital clock and data lines, and the PCB footprint must match the 28-pin SSOP geometry with its 0.65 mm lead pitch.
Được đề xuất
Multichannel Hi-Fi Receiver
The WM8766GEDS/V is appropriate for a high-fidelity multichannel receiver requiring left, right, center, and surround outputs generated from one converter. Its 24-bit data path supports high-resolution source material, and the 192 kHz maximum rate accommodates high-rate digital audio streams. DSP and I2S connectivity provide selectable integration methods with compatible audio processors. Because six DAC outputs must remain usable simultaneously, engineers should verify the required output mode, analog signal path, channel mapping, and load conditions against the official datasheet before finalizing the receiver schematic.
Được đề xuất
Automotive Audio System
The WM8766GEDS/V can support multichannel automotive audio architectures where a central audio controller drives several output channels. Six 24-bit channels at up to 192 kHz suit infotainment and surround-sound configurations, while the 2.7 V to 5.5 V operating range supports integration with embedded power systems. The verified -25 °C to 85 °C specification must be checked against the complete vehicle thermal environment. Production designs should also review EMC, ground-bounce, supply-transient, and automotive qualification requirements separately from the basic DAC functionality.
Được đề xuất
Professional Audio Monitoring
The WM8766GEDS/V is suitable for multichannel monitoring and production equipment requiring a dedicated high-resolution conversion stage. Its six channels can feed separate line-level paths, and the 24-bit resolution and 192 kHz capability align with high-rate digital audio workflows. The converter can receive DSP-formatted data from an audio engine or I2S data from a standard source. Signal-to-noise ratio, total harmonic distortion, output impedance, and allowable loading are not stated in the supplied excerpts and therefore require confirmation from the Cirrus Logic manufacturer datasheet before setting monitor headroom or gain.
Được đề xuất
Digital Audio Player
A network or local-file audio player can use the WM8766GEDS/V to convert digital streams into analog signals for a downstream amplifier. The I2S interface is convenient for common audio SoCs, while the DSP option supports framed source data from compatible controllers. The six-channel output also allows separate conversion for multichannel content rather than requiring multiple converter packages. Integration requires matching the supported sample rate and clocking, providing clean analog and digital supplies, and confirming the converter's output mode before the PCB is released.
Được đề xuất
Multichannel Gaming and Media Console
The WM8766GEDS/V can serve as the multi-output audio converter in a gaming console or media device that supports surround playback. Its six 24-bit channels at up to 192 kHz provide a unified conversion path, and the 28-pin SSOP package is compatible with surface-mount assembly. I2S support simplifies integration with common media processors, while DSP framing can suit controllers with a different serial protocol. Designers must route high-speed digital signals away from analog outputs and apply the manufacturer's recommended grounding and decoupling network.

Ghi chú thiết kế
Keep digital clock, data, and control traces away from the six analog output paths, and follow the partitioning guidance in the Cirrus Logic manufacturer datasheet. Treat the analog and digital supply connections as separate branches until they reach the device-side filtering or decoupling network. The verified package is a 28-pin SSOP with 0.65 mm lead pitch, so the PCB footprint and assembly process must be checked against the controlled package drawing.
Do not assume that a similarly named WM8766 or WM8768 order code is a drop-in replacement. The supplied search results identify WM8766GEDS/RV, WM8768GEDS, and WM8768GEDS/RV, but they do not establish identical pin assignments, temperature grades, clock requirements, or output modes. Compare the official package drawings, pin descriptions, electrical characteristics, and lifecycle records before changing the approved BOM.
Plan the supply network around the verified 2.7 V to 5.5 V operating range. Place the manufacturer-recommended bypass capacitors close to their associated supply pins and provide low-impedance ground returns. Numeric capacitor values, output current limits, and power dissipation were not present in the supplied excerpts, so they must be obtained from the Cirrus Logic manufacturer datasheet rather than calculated from assumptions.
Thông tin tuân thủ
The verified JLCPCB product result identifies the WM8766GEDS/V as RoHS compliant and active. The supplied excerpts do not establish REACH, AEC-Q100 qualification, lead-free status, halogen-free status, or conflict-minerals compliance. The automotive reference describes an application rather than evidence that this order code is AEC-Q100 qualified.
