WM1824BGEDT - 24-Bit 192kHz Stereo DAC | Cirrus Logic
N.º da peça: WM1824BGEDT ✓ AtivoWM1824BGEDT Visão geral
An audio DAC is a signal-conversion integrated circuit that accepts digital audio samples and produces corresponding analog voltage signals. In the product hierarchy, the WM1824BGEDT is a special-purpose ADC/DAC, more specifically a stereo audio DAC, which belongs to the broader family of data-conversion semiconductors. Its role is to convert an I2S data stream into left- and right-channel analog outputs for subsequent amplification, filtering, or line-level routing.
The principal specifications are 24-bit resolution, a 192kHz sampling rate, two-channel stereo operation, and an I2S interface. The 24-bit format provides substantially more numerical resolution than conventional CD-audio formats, while the 192kHz capability supports high-rate digital audio streams. The single-supply architecture simplifies system power planning, and the surface-mount TSSOP package supports automated PCB assembly.
The WM1824BGEDT uses its I2S interface to receive serial digital audio data and stereo channel information. A reconstruction or low-pass filtering stage removes out-of-band digital noise before the analog signals leave the converter. The manufacturer documentation also defines mute attenuation as the level difference between full-scale output and the muted output, providing an important metric for evaluating mute behavior.
Typical uses include digital active speakers, compact stereo audio modules, consumer media equipment, and embedded systems that receive standard I2S audio from a digital audio processor. In each case, the converter is positioned after the digital audio source and before an analog output amplifier or line-output stage. System designers should preserve the required clock relationships, interface format, supply conditions, and analog-output topology from the manufacturer documentation.
A key implementation consideration is the relationship between supply voltage, full-scale output range, and downstream analog headroom. The converter should be placed so that its digital interface and analog outputs meet the source and amplifier requirements without introducing avoidable ground offsets. PCB layout should keep the device close to its decoupling components and route sensitive analog outputs away from fast digital switching nodes.
This page combines the verified WM1824BGEDT identification, package and interface characteristics with application guidance, comparison parameters, and sourcing information. It also distinguishes the verified tube-packaged ordering option from other manufacturing or reel-code variants rather than presenting them as electrically different replacements.

Aplicações típicas
WM1824BGEDT é adequado para 6 aplicaçãos: Digital Active Speakers, Consumer Stereo Audio Modules, Communications Audio Terminals, Embedded Multimedia Systems, Digital Audio Development Boards, Audio Signal-Chain Prototyping.
Digital Active Speakers
The WM1824BGEDT fits the digital-to-analog stage of a powered speaker because it converts a two-channel I2S source into left- and right-channel analog outputs. Its 24-bit resolution preserves the numerical depth of the incoming audio data, and its 192kHz maximum sampling rate supports high-rate source streams. Place the converter between the digital audio processor and the analog power-amplifier input, then follow the manufacturer grounding and filtering guidance. Validate clock relationships and full-scale output headroom before connecting the amplifier, since the single-supply architecture and analog output range determine how cleanly the DAC integrates with the downstream gain stage.
Recomendado
Consumer Stereo Audio Modules
The WM1824BGEDT is suitable for compact stereo modules that accept digital audio and provide analog line-level outputs. Its two-channel architecture avoids duplicating separate single-channel converters, while the I2S interface supports connection to a common digital audio controller. The 16-pin TSSOP package also supports automated surface-mount assembly. In a multi-board consumer product, maintain a continuous ground reference between the digital source, DAC, and output amplifier. Confirm the device's accepted clock and data format and implement the documented low-pass filtering path to remove out-of-band switching artifacts before the analog output reaches downstream circuitry.
Recomendado
Communications Audio Terminals
The WM1824BGEDT can serve as the playback converter in communications equipment that receives a digital I2S stream and needs discrete analog stereo outputs. Its 24-bit data format provides high numerical resolution, and the 192kHz capability accommodates high-rate audio channels when the associated source and transport support that rate. The device should be positioned close to the audio-processing circuitry to minimize digital routing exposure. Apply the manufacturer's recommended bypass and grounding arrangement, and verify the exact output reference and mute behavior during system bring-up so the terminal remains stable when the local amplifier is disconnected or the audio channel is inactive.
Recomendado
Embedded Multimedia Systems
The WM1824BGEDT is appropriate for embedded audio subsystems that use a digital audio processor and require an analog stereo output. Its 24-bit resolution is useful when the signal chain is designed to retain fine amplitude information, while its maximum 192kHz sampling rate supports high-rate stream modes. The TSSOP package fits conventional mixed-signal board assembly and keeps the converter electrically close to the processor. Separate the I2S data and clock routes from analog outputs, use a stable ground reference, and follow the released datasheet for capacitor selection and output filtering. Validate mute startup behavior when the system must avoid audible transients.
Recomendado
Digital Audio Development Boards
The WM1824BGEDT can be used to develop and validate digital-to-analog playback paths because its I2S interface, stereo outputs, and 192kHz capability support direct connection to common embedded audio controllers. Designers can use the device to evaluate channel routing, mute operation, output filtering, and downstream amplifier compatibility. The 16-pin TSSOP package is also convenient for compact prototype layouts. For meaningful measurements, observe the datasheet's output configuration and test conditions rather than inferring performance solely from the nominal sampling rate. A shielded, low-noise test environment helps distinguish genuine converter performance from noise introduced by the board, source, or measurement equipment.
Recomendado
Audio Signal-Chain Prototyping
The WM1824BGEDT supports prototype signal-chain testing where a digital audio stream must become an analog stereo signal for further processing. Its 24-bit format and 192kHz maximum rate provide a suitable test target for clocking, channel alignment, and analog output behavior. Place the converter near the digital source during prototyping to reduce data-line sensitivity, and route its analog outputs toward the next gain or filter stage. Use the manufacturer pin descriptions and reference circuit to establish supply, grounding, and filtering. The documented mute attenuation provides an additional way to verify that the output path responds correctly when the mute state changes.

Notas de projeto
Separate the I2S data and clock routes from the analog output traces, and place the WM1824BGEDT close to its required bypass components. Keep the digital source, DAC, and downstream amplifier on a consistent ground reference. Avoid routing analog outputs beside high-current switching nodes or digital clock edges. The exact pin placement and grounding configuration must follow the manufacturer datasheet and reference circuit.
Do not assume that every ordering suffix represents an electrically different converter. WM1824BGEDT/R is identified as a complete replacement for WM1824BGEDT because the package, terminals, principal performance, and functional characteristics are consistent. Still verify the required tube or reel format and production marking requirements. Supply limits, accepted I2S mode, output reference, and mute logic must be checked against the released datasheet before assembly.
Treat the I2S clock, data, and word-select connections as a matched digital interface and keep them away from the analog outputs. Follow the documented output low-pass filter to remove out-of-band noise. When evaluating the audio path, use the datasheet's mute-attenuation definition and test conditions rather than comparing mute behavior with a differently configured converter. Confirm that the downstream amplifier has adequate headroom for the selected analog output level.
