WM8524CGEDT - 24-Bit 192kHz Stereo DAC | Cirrus Logic
部品番号: WM8524CGEDT ✗ 生産終了WM8524CGEDT 概要
A digital-to-analog converter, or DAC, is an integrated circuit that converts digital audio samples into a continuous analog voltage. The WM8524 belongs to the stereo DAC hierarchy within signal-conversion ICs and broader data-conversion semiconductors. Its 24-bit resolution supports high-fidelity playback, while its 192 kHz sampling capability accommodates high-resolution digital audio streams.
The WM8524's principal output feature is a 2 V RMS ground-referenced line-level signal for each stereo channel. Unlike a conventional line-output stage that requires large coupling capacitors, its DC servo removes the output DC offset and allows ground-referenced operation. This architecture also effectively reduces power-on pops and clicks and allows the device to drive line outputs without output coupling capacitors.
An integral charge pump generates the internal voltage required by the output stage, allowing the converter to operate from a single 3.3 V power rail. The hardware control interface provides a means to configure operating behavior without relying exclusively on software writes, while the I2S interface accepts digital audio data from a host processor, audio codec, or digital audio source.
Typical applications include powered speakers, stereo audio source equipment, consumer media systems, digital audio accessories, and compact soundbars. In these systems, the WM8524 can provide a direct stereo line-output stage with ground-referenced signals. The 16-pin TSSOP package also supports compact board layouts, although careful decoupling and output routing remain necessary for low-noise audio performance.
When designing a circuit around the WM8524, follow the manufacturer datasheet for power, analog, digital, and clock connections. Place bypass capacitors close to their associated supply pins, route the I2S clock and data traces away from the analog outputs, and use appropriate output protection for externally accessible line connectors. Confirm the supported master-clock, sample-rate, and serial-interface configuration before finalizing the digital audio path.
This product resource adds application-specific circuit guidance, lifecycle information, package details, and a structured comparison of the WM8524 with related stereo DAC families. It is designed to help engineers evaluate the converter against functional alternatives while clearly separating package-compatible drop-in replacements from devices that require a different footprint or interface.

主な用途
WM8524CGEDT の用途: 6 件s: Powered Speaker USB Audio Interface, Compact Stereo Media Player, Digital Audio Accessory, Soundbar Front-Panel Audio Output, Network Audio Decoder, Digital Audio Recording and Playback Deck.
Powered Speaker USB Audio Interface
The WM8524CGEDT fits a powered-speaker interface that accepts digital audio from a USB audio bridge or host processor and produces a conventional stereo line signal. Its 24-bit conversion and 192 kHz sampling capability support high-resolution sources, while the 2 V RMS ground-referenced outputs provide a useful line-level drive for the downstream amplifier. The single 3.3 V supply simplifies rail planning, and the DC servo removes the need for output coupling capacitors. Verify the required master-clock and I2S mode with the source device before laying out the board.
おすすめ
Compact Stereo Media Player
In a compact stereo media player, the WM8524CGEDT can convert an I2S stream into left and right line outputs without a separate charge-pump circuit or conventional output coupling capacitors. The 24-bit, 192 kHz converter supports high-resolution playback, while the 2 V RMS output level suits many headphone-buffer or line-amplifier inputs. Its 16-pin TSSOP package conserves board area. The layout should keep the digital bus and clock away from the analog outputs and follow the manufacturer bypass-capacitor recommendations.
おすすめ
Digital Audio Accessory
The WM8524CGEDT is appropriate for a digital audio accessory that receives I2S audio and exposes analog stereo outputs. Its single 3.3 V operating rail simplifies integration with portable or powered accessories, and the 24-bit, 192 kHz conversion capability preserves high-resolution source data. Ground-referenced 2 V RMS outputs eliminate the usual line-output coupling capacitors, while the DC servo helps suppress startup transients. The final product still needs appropriate connector protection and an output-impedance strategy that remains compatible with the intended analog load.
おすすめ
Soundbar Front-Panel Audio Output
A soundbar can use the WM8524CGEDT to convert a decoded I2S audio stream into a stereo line-level output for the main amplifier section. The converter supports 24-bit data and sampling rates up to 192 kHz, allowing the design to preserve source fidelity. Its 2 V RMS ground-referenced output stage avoids large coupling capacitors, and the 3.3 V supply requirement simplifies rail distribution in a multi-rail audio system. Keep the output path short, provide suitable protection at external connectors, and confirm that the upstream processor supplies a supported clock configuration.
おすすめ
Network Audio Decoder
The WM8524CGEDT fits a network-audio decoder after a processor has recovered digital audio from a network stream. The 24-bit, 192 kHz stereo DAC provides a direct conversion path to a line-level analog output, while the hardware control interface supports board-level operating-mode management. Ground-referenced outputs and the integrated DC servo simplify the analog output network and reduce startup transients. In a network product, isolate noisy switching regulators and digital clock routing from the converter, and use the manufacturer's recommended grounding and decoupling arrangement.
おすすめ
Digital Audio Recording and Playback Deck
The WM8524CGEDT can provide the playback side of a digital recording or monitoring deck that converts stored or streamed I2S audio into an analog stereo signal. Its 24-bit resolution and 192 kHz support accommodate high-resolution monitoring workflows, while the 2 V RMS outputs provide a useful line-level interface for downstream amplification. The missing output coupling capacitors reduce the number of bulky passive components, and the compact 16-pin TSSOP package assists board-space reduction. Validate clock ratios and supported serial modes against the playback engine.

設計ノート
Place the required bypass capacitors adjacent to the corresponding power and ground pins, and keep the analog output routing short and symmetric. The I2S data, clock, and master-clock traces should be routed on the digital side of the board and kept away from the 2 V RMS output nets. A quiet return path for the converter and analog amplifier is especially important because the ground-referenced outputs can return signal currents directly through their output ground connections.
Confirm the supported master-clock ratio, I2S format, data alignment, and sample-rate range before connecting the digital audio source. Route clock and data traces as a controlled group, terminate or series-damp them if the interconnect is long or electrically slow, and avoid routing the digital bus beneath the analog outputs. These precautions reduce data errors and prevent digital switching activity from coupling into the stereo output path.
Do not assume that a stereo DAC with similar resolution and sample rate is a drop-in replacement. The WM8524CGEDT uses a 16-pin TSSOP package, but equivalent devices can differ in pin count, pin assignment, supply rails, clock requirements, control signals, and output topology. Compare the manufacturer pin descriptions and application circuits before changing the schematic or placing a substitute on an existing PCB.
The converter operates from a 3.3 V rail and includes an internal charge pump, but external supply design still determines noise performance. Provide a low-impedance 3.3 V source, follow the manufacturer capacitor recommendations, and isolate the analog section from high-current switching and digital processor rails where practical. Avoid sharing narrow power paths between the DAC and motors, loudspeaker amplifiers, or other high-transient loads.
